    摘要: The invention relates to a data processing method for a multistatic radar system comprising a plurality of transmitters and receivers, each receiver being associated with one or more transmitters so as to form one or more bistatic bases. According to the invention, the method involves producing and sustaining multi-receiver Cartesian tracks from bistatic blips produced by the various receivers, and comprises: a first step in which mono-receiver Cartesian tracks are produced and sustained, each mono-receiver track consisting of blips formed by a given receiver; and a second step in which multi-receiver Cartesian tracks are produced and sustained, each multi-receiver track being constituted by merging the mono-receiver tracks together and with bistatic blips which have not been associated with a mono-receiver track. The produced tracks are transmitted together with the attributes thereof to processing means operating upstream from the method.

    摘要: System for dynamically tracking a position of a target with an antenna in a communication system. The system includes an antenna system (410) configured for generating a sum and difference antenna pattern (201-1, 201-2). A sum RF channel (401) is coupled to a sum channel output of the antenna system. A difference RF channel (402) is coupled to a difference channel output of the antenna system. An RF coupler (422-1) is provided that has a first input coupled to the sum RF channel and a second input coupled to the RF difference channel. One or more coupling control devices (418-1, 418-2) selectively vary an effective coupling value as between the difference channel and the sum channel. An antenna tracking error signal is generated at an output of the coupler.

    摘要: The directional antenna apparatus of a base station, after sensing the direction of an undesired wave, calculates the optimum amplitude weighting coefficients and optimum phase weighting coefficients for a plurality of directions between the move starting point and move end point of a mobile station and creates a reference table. Then, when receiving a request for communication from the mobile station, the directional antenna apparatus reads weighting coefficients from the reference table, sets them in each antenna element, and points the directivity toward the mobile station, and starts communication. Then, calculating the time when the mobile station arrives at the position corresponding to each direction from the destination of the mobile station and its moving speed, and reads one by one the optimum amplitude and phase weighting coefficients from the reference table, and sets them in each antenna element, and communicates with the mobile station, while tracking the mobile station.

    摘要: A target tracking radar system for a guided missile wherein sum and difference signals from a reception antenna are multiplexed at a variable rate into a single channel receiver, the multiplexing rate depending on an alternating reference signal. The output of the receiver is applied to a phase sensitive detector operating in synchronism with the alternating reference signal and whose output is utilised to guide the missile towards the target. The detector output is also integrated and applied to circuit means which produces the reference signal, thereby forming a closed loop. The integrated detector output is also applied to a servo motor which drives the antenna to track the target.

    摘要: A monopulse radio direction finding and tracking system having the capacity of detecting the presence of multiple radiating sources within the effective beamwidth of the monopulse antenna and causing the monopulse antenna to move toward and align its boresight with one of the multiple sources. Signal processing is provided that implements an algorithm based on the amplitudes and absolute magnitudes of signals from a receiver sum channel, elevation and azimuth difference channels, and elevation and azimuth angular error channels. The algorithm utilizes the differences in the ratio of signals present in these channels when a single radiating source is present and when multiple sources are present. Steering control circuits are provided that bias the azimuth and elevation antenna steering servo system to cause the antenna to align its boresight with one of such multiple sources. The improved monopulse tracking system is applicable to a missile guidance system providing terminal guidance to cause the missile to intercept one of multiple radiating targets. Means are provided to accommodate multiple sources or targets in any orientation with respect to the monopulse antenna azimuthal and elevation planes.
