摘要
调频连续波雷达在近距离探测中具有重要的应用价值,而基于三角调频连续波的雷达通过对回波上下两个变频周期的联合分析,可以在一个扫频周期内获得目标的距离及其多普勒中心频率。本文将从三角调频连续波信号模型出发,分析目标相对雷达运动引起的多普勒频移,以此为基础进一步分析一种多普勒检测算法及速度距离耦合引起的测量误差,然后还通过仿真实验检测算法及其抗噪声性能。
FMCW radar is of great importance in the field of short distance detecting, and with the combined analysis of the up and down chirp periods, triangle FMCW radar can obtain both the Doppler and the range information of the target in a single sweep period,. This paper will start from the signal model, analyze the Doppler induced due to the relevant moving between radar and the target, and carry on analyzing a Doppler detecting method and error induced by the coupling of the speed and the range detection. Then simulations are taken to test the detecting algorithm of Triangle FMCW Radar, test performance of the algorithm on anti-noise.
