摘要： A protective system for a vehicle-borne tracking radar, designed to counter the effect of an off-target jammer whose interfering signals are picked up by a directive antenna together with echoes from an actual target, comprises a receiver with a sum channel and a difference channel. In the absence of a jammer, the sum channel is connected via a signal processor to telemetric circuitry in the radar associated with the vehicular guidance system which keeps the antenna axis trained upon the target as the vehicle homes in on same. When a strong jamming signal is detected, a switching device in the processor cuts off the sum channel from the telemetric circuitry and supplies the latter, instead, with rectified error signals from the difference channel, these error signals being also delivered prior to rectification to a tracking-control circuit which energizes an antenna rotator to hold its axis in line with the jammer. The presence of a jammer may be detected by a signal-level comparator with two circuit branches connected to the sum channel, these branches including respective integrators which are alternately supplied with incoming signals in a target window and in a jammer window occurring at different instants of a recurrence period. Another possible jammer-signal detector, which may be included in the processor, receives the rectified error signal from the difference channel in the target window and produces a "jammer present" signal whenever the accumulated error signals exceed a predetermined threshold.

摘要： An arrangement for correcting deviations from the true bearing due to the effects of specular reflecting surfaces in target tracking radar installations having at least three primary feeds. At least two of the primary feeds are aligned such that a plane formed by the longitudinal axes of their radiation characteristics is disposed at least approximately perpendicular to the specular reflecting surface. At least one further primary feed is arranged such that the longitudinal axis of its radiation characteristic is located externally of such plane. A summation-difference network produces from the echo signals received by the primary feeds, apart from a summation signal, also two difference signals, and a cross-term signal formed in at least one measurement interval. From these signals there is produced an angle error signal which is divided into two components. In a signal processing stage there is obtained a correction signal in order to correct the angle error signal falsified by the specular reflection effects.

摘要： A sensing system for a vehicle includes at least one radar sensor disposed at the vehicle and having a field of sensing exterior of the vehicle. The radar sensor includes multiple transmitting antennas and multiple receiving antennas. The transmitting antennas transmit signals and the receiving antennas receive the signals reflected off objects. Multiple scans of radar data sensed by the radar sensor are received at a control, and a vehicle motion estimation is received at the control. The control, responsive to received scans of sensed radar data, detects the presence of objects within the field of sensing of the radar sensor. The control, responsive to the received scans of sensed radar data and the received vehicle motion estimation, synthesizes a virtual aperture and matches objects detected in the scans and determines a separation between detected objects by tracking the detected objects over two or more scans.

摘要： A method and apparatus for reducing noise in a coded aperture radar system, the coded aperture radar system transmitting signals which occur in sweeps, with K sweeps utilized to cover field of view of the coded aperture radar system and Q frequency shifts or steps occurring each sweep thereof. An array of N antenna elements is provided, the array of antenna elements each having an associated two state modulator coupled therewith. Energy received at the array is modulated according to a sequence of multibit codes, the number of codes in the sequence of codes comprising at least K times Q times N, thereby reducing noise in the coded aperture radar system compared to a coded aperture radar system radar system having fewer than K times Q times N codes in its sequence of multibit codes.

摘要： The present invention is directed to a ground moving target (GMTI) radar that can detect targets, including dismounts, with very small minimum detectable velocities by combining signals from antennas on different spatially separated platforms in a main beam clutter-suppressing spatially adaptive process without requiring that the relative positions of the antenna phase centers be accurately tracked. The clutter nulling is in addition to that provided by the Doppler filters. The spatial displacement provides a narrow mainbeam clutter null reducing undesired target suppression. The clutter-suppressing spatially adaptive structure is used in both the sum and delta channels of the monopulse processor so that the beam distortion caused by the spatial nulling is compensated for, and the monopulse look-up process is preserved to maintain angle accuracy. Noncoherent integration is employed to recover signal to noise loss resulting from the uncertain relative locations of the platforms.

摘要： A radar system in which Coded Aperture Radar processing is performed on received radar signals reflected by one or more objects in a field of view which reflect a transmitted signal which covers a field of view with K sweeps and each sweep including Q frequency changes. For Type II CAR, the transmitted signal also includes N modulated codes per frequency step. The received radar signals are modulated by a plurality of binary modulators the results of which are applied to a mixer. The output of the mixer, for one acquisition results in a set of Q·K (for Type I CAR) or Q·K·N (for Type II CAR) complex data samples, is distributed among a number of digital channels, each corresponding to a desired beam direction. For each channel, the complex digital samples are multiplied, sample by sample, by a complex signal mask that is different for each channel.
