Estimation of coordinates of ground targets in multi-static forward scattering radar

The paper deals with the problem of measurement of trajectory of moving ground targets by multi-static forward scattering radar (FSR) consisting of several independent transmit positions and one multi-channel receive position. The system of transmit positions is considered to be a multi-frequency thinned transmitting antenna array. To provide unambiguous measurement of the target azimuth, the multi-frequency mode of transmit array is used. The algorithm of space-time signal processing is proposed. The results of mathematical modeling are presented.
