摘　　要：该文提出了一种适用于连续波雷达测速的、稳健的离散频谱校正方法,即三角形法。该方法具有原理简单、计算量小、易于实现、校正精度高等优点。该文介绍了三角形法频谱校正的原理,分析了三角形法校正效果随信噪比以及参与校正的谱线根数变化情况,并给出了仿真结果。最后将三角形法和能量重心法进行了对比,得出了三角形法受信噪比变化影响较小的结论。A robust correcting method for discrete spectrum in CW radar velocity measuring is proposed in this paper, t is named the method of triangle. This method, with low compution and high accuracy, is theoretically simple and easily carried out. The paper introduces the principle of this method, analyzes its correcting effects changed with noise and spectrum line numbers used, the simulation result is also given. Finally, the method of triangle is compared with energy centrobaric correction method, with the conclusion that noise has less effects on the method of triangle.
