摘要
本文首先给出了圆锥扫描步进频率雷达信号的形式 ,并利用归一化的表达式对圆锥扫描和步进频率之间的互相影响进行了详细分析。论证了该信号可以在距离高分辨率的基础上针对单个散射中心进行有效测角。同时在此基础上提出并实现了一种紧耦合角度处理方案 ,给出了计算机仿真结果 ,并讨论了噪声和运动等非理想因素对该方案的影响。紧耦合角度处理方案已经在某实时信号处理系统中得到了实现。计算机仿真结果和外场实验结果都证明了该方案有效性。
The form of conical scan, step frequency radar waveform was first given, and the interaction of conical scan and stepfrequency was analyzed based on the given expressions. The conical scan, step frequency radar waveform can get the angular information as well as the range information of range closed targets. The close coupling processing method was developed. Some undesirable factors such as noise and motion were analyzed. The close coupling processing method has been implemented in a real time radar signal processing system. Results of both computer simulations and practical experiments have proved that this algorithm is effective.
