摘要：
Frequency diverse array (FDA) radar transmitting coherent waveforms employs frequency increment between the array elements. It is capable of providing range-angle-time-dependent transmit beampattern. Aiming at the receiving processing of such coherent FDA radar, a two dimensional angle-time matched filter is proposed, which is capable of performing matched filtering in fast-time domain and realizing equivalent transmit beamforming. This is different from the traditional matched filtering process. Moreover, a partially matched filtering approach in angle-time domain is devised by considering some particular applications. By dividing the whole pulse duration into several sub-pulses, the received echo is processed by the angle-time matched filter modulated by the transmit beampattern. Simulation examples are provided to demonstrate the effectiveness of the proposed approaches for the coherent FDA radar. © 2018, Editorial Office of Systems Engineering and Electronics.
