摘　　要：针对随机Hough变换法(RHT)只适应于稀疏杂波环境且最大采样次数Kmax难于选取等问题,本文提出一种改进的随机Hough变换法(MRHT),对RHT算法加入了采样终止准则和约束条件限制。仿真实验表明,该算法与RHT相比,不仅有效的减少了虚警航迹概率,而且在计算时间方面大大减小,适于工程应用。In view that Randomized Hough Transform （RHT） is only applicable in sparse clutter circumstances and the maximum sampling times K is hardly selected, a modified Randomized Hough Transform （MRHT） method is presented, in which the RHT algorithm is added with sampling ending criteria and constraint condition limit. The simulation test shows that the MRHT decreases the false-alarm rate of initial track effectively and reduces computation time greatly, compared with the RHT algorithm. The proposed method is suitable for application in engineering.
