摘要
二次差频测距具有原理简单、结构设计相对容易等优点,文中将其应用于边搜索边跟踪模式。在介绍了二次差频测距基本原理的基础上,对该体制雷达的重难点问题隔圈解距离模糊开展研究。首先给出了隔圈解距离模糊方法,然后讨论了目标有效性判决问题,最后通过仿真验证了方法的有效性。
Based on advantages such as simple principle and easy design of structure,the quadric difference frequency ranging method is applied to TWS mode.The principle of quadric difference frequency ranging is introduced,in this paper and the important and difficult problem is studied： resolving range ambiguity for neighboring circles.Firstly,the range ambiguity resolving method for neighboring circles is given.Then the judging of target effectivity is discussed.Finally,simulation results verify the validity of the method.
