Analysis and Research on Composite Modulation Algorithm

从低截获雷达的实际需求出发，针对线性调频信号在中／高速目标中存在的多普勒跨越问题，提出双线性调频复合算法。对算法进行了理论分析和仿真研究，并给出了基于实测数据的测试结果，并与常规处理算法进行了比对，证明了算法的有效性，具有较高的工程应用价值。

Proceeding from the requirements of LPI radar in practical application and the problem of Doppler cross caused by high-speed target motion during coherent accumulation period for linear FM signals, a dual linear FM composite algorithm is proposed. The theory analysis and simulation for the algorithm are presented and the real result is provided. Comparing with the conventional algorithm used, the composite algorithm has been proven highly effective and can be used for engineering.
