| 摘 要： | 报道了一类由二相编码信号与线性调频信号组合而成的新的脉冲压缩信号。导出了这类信号的表达式。通过理论分析和计算机模拟，给出了该类信号的模糊函数(图)，幅度谱特性，匹配滤波器输出波形，多普勒频移特性，有加权时的压缩脉冲时间旁瓣波形和低截获概率等方面的性能。分析证明，该类信号与线性调频信号或二相编码信号相比具有更好的低截获概率特性，其多普勒性能优于二相编码信号。

| Abstract: | One kind of new pulse compression radar signal obtained by combining chirp waveform with binary pseudorandom sequences is discussed. Through the theoretical analysis and computer simulation, several main characteristics of the radar signal are discussed, such as the ambiguity function, ambiguity graph, the spectrum, the response of the processing filter and the low probability of interception. The results show the effectiveness of the new radar waveforms on the performance of high resolution and low probability of interception. |
