摘要： A radar monopulse signal receiving system according to an aspect of the invention provides sum (&Sgr;) and a single difference (&Dgr;) beam outputs from the beamformer. This is accomplished by encoding the information relating to the azimuth and elevation difference beams onto a single complex number. By comparison with some prior-art arrangements, the number of channels required for processing the signals is reduced. Near the end of the monopulse processing, the quotient is taken of complex number divided by the sum beam information, which directly produces a complex monopulse ratio m=mA+jmE. The azimuth and elevation monopulse ratios are represented by mA and mE, respectively.

摘要： A monopulse radar equipment is developed which comprises first and second radiators arranged in symmetrical positions with respect to the boresight axis to radiate radar pulses in a predetermined cycle and thus to produce first and second directional radiation patterns, a beam forming network for synthesizing in an in-phase and opposite-phase relation the first and second directional radiation patterns of the first and second radiations into sum and different patterns, and a multichannel receiver for forming from the sum and difference patterns an off-boresight signal representing a deviation of a target object from the boresight direction and a sidelobe suppressed signal resulting from suppressing a sidelobe response of the sum pattern. The first and second directional couplers are interposed on the sum and difference pattern signal transmission channels between the beam forming network and the multichannel receiver. The first and second calibration signals of the same amplitude and phase are injected onto the sum and difference pattern signal transmission channels through the first and second directional couplers. The calibration signal is detected at the output terminal of the multichannel receiver and the phase characteristics between the sum and difference pattern signal transmission channels are compensated for in accordance with a result of detection.

摘要： An internal impedance dependent amplifier has a gain as determined by the impedance at a predetermined node within the amplifier. A PIN diode is coupled to the predetermined node. The PIN diode is driven with a forward biased current which serves as the accurate gain control (AGC) signal for the amplifier. In the preferred embodiment, the PIN diode is driven by an operational amplifier in such a manner that the impedance thus coupled to the predetermined node in the amplifier is temperature independent. Because the PIN diode has an impedance given by:log R=A+B log Ip,whereR is the impedance of the PIN diode;IP is the forward biasing current; andA and B constants which are different for each PIN diode,the AGC voltage applied to the operational amplifier driving the PIN diode is linear with respect to the impedance of the PIN diode and hence is also linear with respect to the voltage gain of the impedance controlled amplifier to which the PIN diode is coupled. This characteristic of the gain of the amplifier allows the amplifier to be cascaded in series and to preserve the same impedance relation as expressed above for the cascaded series of amplifiers as well. Thus, the gain in dB of the cascaded series of amplifiers is log linear with respect to a common AGC voltage applied to each of the amplifiers of the series.

摘要： An improved monopulse radar system wherein target return signals received by a plurality of antenna elements are corrected with correction signals derived within the system in response to pilot pulses. The improvement comprises a plurality of receiver channels, each receiver channel being coupled to a single one of the plurality of antenna elements. The improvement also comprises means for generating a first set of quadrature components of video signals developed in the plurality of receiver channels in response to the pilot pulses received by the plurality of antenna elements, and for generating a second set of quadrature components of video signals developed in the plurality of receiver channels in response to return signals from the target received by the plurality of antenna elements. Digital signals representative of the first and second sets of quadrature components of video signals are generated. The digital signals representative of the second set of quadrature components of video signals are digitally corrected with the digital signals representative of the first set of quadrature components of video signals to produce digital signals representative of corrected target return signals. Signals corresponding to the angle of the target relative to the plurality of antenna elements are generated in response to the digital signals representative of corrected target return signals.

摘要： A monopulse antenna system providing a pair of phase/amplitude related signals in response to the reception of a desire signal, having calibration correction means attached thereto which receive one of the output signals from the antenna system and produce a pair of output signals having equal amplitude and a 90 degree phase difference. The calibration correction circuitry supplies the pair of output signals to the two channels of the monopulse receiver which includes circuitry for comparing the amplitude of signals in each of the channels and standard monopulse circuitry which compares the phase of signals in the two channels. Gain and phase adjustments in at least one of the channels are adjusted in response to the pair of signals until the compared output signals are equal in amplitude and 90 degrees apart in phase.

摘要： This is a monopulse system for deriving the azimuth and elevation error signals in a single channel, eliminating the second error channel used in the conventional monopulse systems and reducing the number of channels required for the sum azimuth and elevation error signals from three to two channels. This reduction from three to two channels is accomplished by introducing a mode generator in the throat of the feed horn. The mode generator selectively changes the phase of signals in certain modes while leaving the phases of other modes uneffected. These selected signals are processed through a circular polarizer which introduces a time phase delay to the signals unaffected by the mode generator so that in the single error channel two signals appear, the azimuth and the elevation error signals, with the elevation error delayed 90* in relation to the azimuth error. These signals are in phase quadrature, can be processed by basic phase comparison techniques and the azimuth and elevation and error information can be separately extracted.
