用于提高米波搜索雷达测角精度的虚拟阵列方法

A Suppositional Array Method Used to Improve The Accuracy of The Measuring Angle for Meter Wave Search Radar

本文介绍一件虚拟阵列法．可提高米波搜索雷达的四角精度．当波束扫描时．利用二元阵列天线接收到的单个目标的回波脉冲串包络．经这种方法处理后．可与Ｎ元钱阵接收到的脉冲串包络等效，测角精度得到明显改善．这种方法尤其适用于舰载小型米波拉索雷达．文中还给出了模拟计算结果，并提出了一种简单有效的测量相位差的方法。

Describes a suppositional array method used to improve the accuracy of the angle to be measured by meter wave search radar. When the beam scanning.after procesing by means of this method,the envelop of the echo pulse train received by array with two elements from single target may be equivalent to that one received by the linear array with N elements. Therefore the remarkable improvement of angle accuracy is obtained. This method is specially suitable to the marine meter wave searchradar. The simulating calculating ronlts are given and a simple effusive method used to thediffetencc of phase is Presented in this peper.
