摘　　要：以提高高频雷达分辨力和抗干扰能力为目的,利用准随机跳频原理与互补P4码设计出脉内互补P4码调相脉间准随机跳频雷达信号,给出了该信号的参数设计原则、模糊相关特性及距离速度信息提取方法。仿真结果证明,该信号与传统高频雷达信号相比,具有多普勒容限更大、分辨力更高、抗干扰能力更强的优点。For the purpose of improving resolution and antijamming capabilities of high-frequency Radar, a new waveform which is co-modulated by complementary P4 Phase-coded signal and by quasirandom frequency hopping signal is proposed. According to the characteristic of the signal, signal processing scheme of range information and velocity information is introduced. The simulation results demonstrate that the waveform proposed in this article possesses both higher resolution and stronger anti-interference characteristic prior to conventional radar signal.
