Abstract:

It is difficult to give consideration to both the maximum unambiguous velocity and the minimum detectable velocity (MDV) simultaneously in the single frequency uniform linear array radar system. A non-uniform linear array radar system with multiple carrier-frequencies provides an approach to settle the problem.However,the detect performance is impacted by the array pattern and frequency values,which need to be optimized to reach the best detect result.A space-frequency joint optimization method to minimize the ndetected velocity region is presented,which performs better when compared with a cascade optimization method under limited conditions.A preliminary result against an airborne simulation data demonstrates the effectiveness of the proposed method.
