Abstract
Estimation error of coherent parameter will decrease the coherent performance of distributed coherent aperture radar (DCAR). The evaluation of coherent performance in real time will determine the subsequent work mode of the DCAR. Therefore, a real-time monitoring method of coherent performance should be researched to establish a closed-loop workflow system. In this paper, an estimation method of coherent efficiency of DCAR based on cross correlation is proposed. Firstly, the transmitting coherent efficiency and the receiving coherent efficiency are defined via the cross correlation, which are the composition of full coherent efficiency. In the following, the received echo is modified by unit radar according to coherent parameters, and then the coherent performance is estimated by cross correlating the transmit signal and the modified echo signal. In the end, the simulation is carried out and verifies the effectiveness of the proposed method.
