摘要
圆锥扫描线性调频连续波是一种简单易行的高分辨雷达体制。分析了圆锥扫描与线性调频连续波的兼容性,讨论了两者之间的相互影响,提出了基于散射点高分辨距离像的频域测角方法,并详细推导了具体的公式。仿真结果表明,该方法在通常的末制导雷达回波信噪比条件下具有较高的精度和可实现性。
Conical scan LFMCW radar is a simple and practical high-resolution radar system. The compatibility of the conical scan with LFMCW signal is analysed,and their mutual influences are discussed. The angle - measure method in frequency domain is presented based on the high range resolution profile of each scattering centre, and the precise angle-measure formula in detail is deduced, which are proved to he precise and feasible by computer simulations.
