摘要
脉压信号因能较好的解决作用距离和分辨能力之间的矛盾以及良好的抗干扰性能得到了广泛的应用。常用的脉压雷达信号为线性调频信号和相位编码信号,而组合脉压雷达信号在抗干扰能力方面更有优势。文中通过仿真计算,使用多种干扰样式,对两种组合脉压雷达信号的抗干扰性能进行了定量分析。计算结果及仿真试验表明,其抗干扰性能优于纯线性调频信号或相位编码信号。
The pulse compression （PC） radar signals are widely used because of their good range coverage and resolution, and also the nice performance of anti-jamming. The commonly used pulse compression radar signals are the linear frequency modulation （LFM） signals and the phase encoded signals, while the combination PC signals consisting of several PC radar signals may perform better in anti-jamming. In this paper, the anti-jamming abilities of two kinds of combination PC signals are quantitatively analyzed and verified through theoretical computation and simulation under many styles of jamming.
