脉内线性调频、脉间二相码混合信号的脉冲压缩方法与性能分析

Digital Processing and Analysis of the Mixed LFM-BC Signal

提出一种由线性调频与二相码组合而成的新型混合脉冲信号,给出了其数学表达式、处理方法及其模糊函数的表达式。通过对该混和信号的性能分析,发现该信号具有更高的距离、速度分辨率,以及更好的低截获概率特性。

According to a new type of mixed pulse compression signal, this paper discusses the mathematical expression, the way of processing and the expression of the ambiguity function. Through the analysis of the mixed signal, it is found that this signal has the higher rangevelocity resolution and the lower LPI property.
