摘要： A vehicle positioning and tracking radar system includes a rotating antenna with a pair of spatially separated transmit feeds for simultaneously transmitting a pair of frequency-modulated continuous-wave (FMCW) electromagnetic signals having a first polarisation and a pair of spatially separated receive feeds for receiving an electromagnetic signal having a second polarisation, wherein the first and second polarisations are different from one another, such that the transmit feed and receive feed at the rotating antenna are isolated from each other; and a coded modulated transponder receives transmit signals from the rotating antenna with the first polarization and transmits a receive signal to the rotating antenna with the second polarization.

摘要： An antenna comprised of a plurality of identical subarrays each having N antenna elements. The antenna elements of a core of subarrays all contribute outputs which are used for forming sum and difference beams. A peripheral area surrounding the core has subarrays which have a lesser number of antenna elements which participate in the signal processing operation to derive the sum and difference beams. The antenna elements of each subarray are combined in a manifold having one output, for the peripheral subarrays, and three outputs for the core subarrays. The manifold outputs are provided to various digital receivers which process the manifold signals with predetermined weighting functions. A digital beamformer processes the digital receiver outputs to derive the sum and difference beams which are used by a radar processor for tracking targets.

摘要： A receiver that selectively samples a received signal in order to suppress an interference component of the signal while recovering a desired component. The selective sampling may be accomplished by low cost, low complex analog or digital circuitry. The receiver includes a first input that receives a first signal, including a desired signal component and an interference signal component and a second input that receives a second signal including the interference component only. The first and second signals are then provided to the sampling circuitry. First, the phase of the interference component of the both the first and second signals is aligned. Next, the points in a wave cycle that the second signal is at a power minimum are detected. Finally, first signal is sampled close to the point when the second signal is at the power minimum to recover the desired signal component and suppress the interference component.

摘要： In a microwave communications link, an antijamming antenna system with enhanced main beam nulling is realized by providing gain in the difference port output of a monopulse antenna compared to the sum port. As a consequence interference signals are nulled out at much closer angles to the desired signal than is the case when the gain is the same in both channels. The gain is introduced when a dominant jammer is detected. Detection of a dominant jammer is identified for the conditions in which the monopulse sum channel power level exceeds the sum of the difference channel power levels and the system processor output signal/noise ratio is unsatisfactory.

The method comprises the steps of processing the sum, elevation difference, azimuth difference, and double difference signals in accordance with a series of linear equations to obtain a set of intermediate values; and processing the set of intermediate values in accordance with a set of algebraic equations to obtain signals representing an angular direction of each of the plural targets. Preferably, the method further includes the step of processing the sum, elevation difference, azimuth difference and double difference signals and the signals representing the angular directions of the targets according to a further set of algebraic equations to obtain signals representing the amplitude of the beam reflected from each of the targets. Also, in a preferred embodiment, the signals representing the angular direction of the targets include signals representing, for each of the targets, an angular direction of the target in an x-plane, and an angular direction of the target in a y-plane.

摘要： A system and method for estimating azimuth angle, elevation angle and signal detection and which includes an antenna system having a plurality of elements, each element receiving a different concurrent portion of an incoming analog signal having a real and an imaginary portion. A converter is provided for each antenna element for converting each analog signal to digital form. A processor is provide for multiplying the sum of the real parts of the signals from a first group of the elements with the conjugate of the sum of the remainder of the elements to provided an estimated azimuth, elevation of signal detection measurement. In the case of a four element antenna, AzEst=Angle((A+B)*(C+D)Conjugate))=(x.sub.A +iy.sub.A +x.sub.B +iy.sub.B)*(x.sub.C -iy.sub.C +x.sub.D -iy.sub.D), ElEst=Angle((A+D)*(B+C)Conjugate))=(x.sub.A +iy.sub.A +x.sub.D +iy.sub.D)*(x.sub.B -iy.sub.B +x.sub.C -iy.sub.C) and Magnitude ((A+B*(C+D)Conjugate)) or Magnitude ((A+D*(B+C)Conjugate)). When the antenna system includes four antenna quadrants A, B, C and D, false detections due to responses coming from the sidelobe regions are suppressed by subtracting the offset OffsetAz=ScaleFactor*Magnitude(DeltaAz), where the offset is a scale factor to make the numbers come out correctly to provide a synthetic beam response: SyntheticAz=Magnitude((A+B)*(C+D)Conjugate)-OffsetAz the processor further including a comparator for comparing the Synthetic Az to a threshold to determine validity of the signal.

摘要： Bearing rate of change, or equivalently bearing differences, are used to estimate emitter geolocation, in contrast to using such rates or differences to estimate only range. In using the bearing differences, it is not necessary to maintain the same relative bearing to compensate for DOA dependent errors. Nor does the invention require a precise fully resolved and calibrated interferometer to generate DF measurements. Furthermore, it can be used with currently implemented amplitude DF systems that employ no phase interferometry at all. By making minimal changes, these systems will produce accurate geolocation. The invention will also work with any system that can be modified to produce an accurate bearing rate-of-change. Therefore, it can be used with time-difference-of-arrival (TDOA) systems also. If bearing measurements are also produced by such systems, the magnitude of the bias on that bearing measurement is not important. The effect of angle bias errors in performing bearings-only geolocation are greatly reduced or eliminated. Bias and random components of the measurement error are separated, an estimation of bias error in azimuth or AOA measurements can also be generated. Bearings differences are uniquely associated with curves, e.g. circles, on which the emitter must lie. A plurality of circles are generated to unamibiguously determine emitter geolocation. Multiple platforms may be used to generate the bearing differences. It is also possible to utilize existing bearings-only emitter location software by generating psuedo bearings. The new pseudo bearing measurements use bearing differences, rather than AOA. Geolocation is thus derived strictly from bearing differences, thus eliminating the effects of bias error.
摘要翻译：使用轴承变化率或等效的差异来估计发射器地理位置，与使用这种速率或差异仅估计范围相反。在使用轴承差异时，不需要保持相同的相对方位来补偿DOA相关的误差。本发明也不需要精确的完全分辨和校准的干涉仪来产生DF测量。此外，它可以与目前实现的振幅DF系统一起使用，这些DF系统根本不使用相位干涉测量。通过进行最小的改变，这些系统将产生准确的地理定位。本发明还将适用于可以进行修改以产生精确的轴承变化率的任何系统。因此，它也可以与到达时差（TDOA）系统一起使用。如果这种系统也产生了轴承测量，则轴承测量的偏差幅度并不重要。在仅执行轴承地理位置时角度偏差误差的影响大大降低或消除。测量误差的偏差和随机分量被分离，也可以产生方位角偏差误差或AOA测量的估计。轴承差异与曲线唯一相关，例如发射器必须在其上。产生多个圆以不明确地确定发射器地理位置。可以使用多个平台来产生轴承差异。也可以通过生成伪轴承来利用现有的仅轴承发射器位置软件。新的假轴承测量使用轴承差异，而不是AOA。因此，地理位置严格来源于承载差异，从而消除偏差误差的影响。

摘要： A three input device which accepts signals from a two port antenna system having opposing cardioid patterns, and a third input for a figure eight pattern that is at right angles to the first cardioids. The first antennas cardioids are combined by a zero-phase hybrid combiner into an omnidirectional pattern. This omnidirectional pattern is combined in a second hybrid combiner with the figure eight pattern so that the sum and difference patterns are present at the outputs. These signals are fed to a processor which decodes the front/rear directional information. To decode left/right directional information, switches bypass both hybrid combiners and feed the first antennas basic cardioid patterns directly to the processor.
