摘要
采用大时宽带宽积信号是同时提高时间和频率分辨力的必由之路,也是在一定的时间和频率分辨力要求下,提高雷达的发射脉冲能量的利用率和杂波抑制能力的有效途径。文中通过对模糊函数的分析,讨论了四种高分辨雷达信号的分辨力、距离-多普勒耦合等性能,介绍了它们获得距离高分辨的处理方法,并说明了在制导中使用它们的优缺点。
It is the only way that big time-wide and band-wide improve the resolution of time and frequency at the same time, and it is an effective approach that improves the utility ratio of transmitted pulse energy and the capability of clutter suppression under the demand of definite resolution of time and frequency. The resolution , range-Doppler coupling and others performance of four high resolution radar signals are discussed, the processing methods of their obtaining high range resolution are introduced ,and the advantage and disadvantage of each high resolution signal used in guidance are analyzed from ambiguity function in this paper.
