A Novel Wideband Distributed Coherent Radar Performance Evaluation Method

The distributed full-coherent radar (DFCR) can achieve a higher SNR (signal to noise ratio) gain by coherent synthesis of the echo from multi-part dispersed mobile radars. Thus people pay more attention to the coherent performance evaluation in DFCR. In order to evaluate the coherent performance more efficiently and accurately, this paper proposed a comprehensive evaluation method which combines the SNR and correlation coefficient to characterize the coherent performance. Simulation results verified the effectiveness of the proposed method.
