Altimetry System of Multiband Pseudo Code Modulation Continuous Wave

针对空空导弹高度测量误差较大,严重制约空空导弹使用范围的问题,提出多波段伪码调制连续波测高系统。基于m序列伪随机码的相关特性,该系统采用C波段加X波段、m序列伪随机码调制、瞬时跳频的连续波复合体制来实现空空导弹的高度测量。仿真验证结果表明,该测高系统精度高、抗干扰能力强,能够满足空空导弹的测高需求。

Aiming at the problem that the height measurement error of air-to-air missile was large and seriously restricts the use range of air-to-air missile,a multiband pseudo random code modulation continuous wave height measurement system was proposed.Based on the correlation characteristics of m-sequence pseudo random code,the system adopted continuous wave compound system of C-band+X-band,m-sequence pseudo random code modulation and instantaneous frequency hopping to realize the height measurement of air-to-air missile.Simulation results showed that the height measurement system had high precision and strong anti-jamming ability,which could meet the height measurement requirements of air-to-air missile.
