摘要
利用多载波余码相位调制(MCPC)雷达信号实现同时极化探测,并通过频率捷变技术可提高MCPC雷达信号的距离分辨率。文中综合同时极化、频率捷变和MCPC雷达探测技术提出了同时极化频率捷变MCPC雷达系统结构,分析了工作原理,设计了同时极化频率捷变MCPC雷达探测波形,并对波形的信号峰值旁瓣比、信号间的独立性、距离分辨率和抗有源干扰能力做了分析和仿真说明。研究表明,同时极化频率捷变MCPC雷达信号能很好地实现同时极化探测,同时提高了原MCPC雷达信号距离分辨率,其抗有源干扰能力随着同时极化数和频率捷变脉冲数的增加而加强。
Multi-carrier complementary phased-coded （MCPC） radar signal is applied for coexistent polarization detection and frequency agility technique is used to improve range resolution for MCPC radar signal. The coexistent polarization frequency agility MCPC radar system is proposed based on coexistent polarization, frequency agility and MCPC radar techniques. Waveform design of coexistent polarization frequency agility MCPC radar is also presented. The analysis and simulation result of signal peak sidelobe level, isolation and anti-jamming capacity shows coexistent polarization frequency agility MCPC radar signal can be used for coexistent polarization detection, and MCPC radar signal range resolution is also improved. Its anti-jamming capacity is improved with the number increase of polarization and frequency-modulated signal pulse.
