摘要
为了解决卫星信号不可用条件下长航时导弹精确导航的问题,提出了一种复用弹载制导雷达进行载体地速测量的一体化设计方案。对“X”型、“T”型天线布局方式下三维地速测量的计算方法进行了推导,设计天线波束参数、波形参数、射频组件和信号处理架构。对该系统的测速误差进行了分析。结果表明,复用弹载制导雷达进行载体地速的辅助测量,能够满足载体导航速度修正的需求,提高了设备集成度。
In order to solve the problem of precise navigation of long endurance missile when satellite signal is unavailable,an integrated scheme for ground velocity measurement of carrier by using missile-borne guidance radar is proposed.The calculation methods of three-dimensional ground velocity measurement with"X"and"T"antenna layout are deduced.The antenna beam parameters,waveform parameters,RF components and signal processing architecture are designed.The measurement error of the system is analyzed.The results show that the auxiliary measurement of carrier ground velocity can meet the needs of carrier navigation velocity correction and improve the equipment integration.
