摘要
文中对机载脉冲多普勒雷达在HPRF(高脉冲重复频率)状态下,使用PRF转换法和线性调频测距的优缺点进行了比较分析,提出了采用二者综合运用的测距方法。结果表明,该方法能够在HPRF工作模式下完成远距离目标速度测量的同时,获得精度较高的距离测量值。
In this Article, The advantages and disadvantages of PILF conversion ranging and linear frequency modulation ranging is compared While HPILF search mode used in airborne PD radar. The integrated ranging method is proposed. Practical results indicate that both velocity measurements and high precision distance measurements are obtained by this method while HPRF search mode.
