本文研究了稀布阵综合脉冲孔径雷达的长时间相干积累特点及其存在的问题;提出了长时间相干积累中一种易于实现的运动补偿方法和基于时频分析的长时间相干积累方法;并给出了计算机模拟结果,结果表明SIAR雷达体制对微弱运动目标有较好的检测性能。
In this paper, we study the long-term coherence accumulation and its existing problems of SARFAM. Propose an easy-to-implement motion compensation method for long-term coherent accumulation and a long-term coherent accumulation method based on time-frequency analysis. The computer simulation results are given. The results show that the SIAR radar system has better detection performance for weak moving targets.
