摘　　要：针对Hough变换参数空间间隔尺度对发现概率的影响,分析了基于Hough变换航迹起始方法在存在正态分布的系统噪色、观测噪声和无噪声3种情况下参数空间矩形带宽度的划分对发现概率的影响,提出了可以补偿测量噪声的参数空间划分方法,仿真结果验证了此方法的有效性和可行性。Aimed at the influence of Hough parameter space granularity upon the probability of track initiation, the probability of track initiation is analyzed according to how to make strips in parameter space in the presence of normal, distributed, additive system noise, measurement noise and without any noise.A new parameter space structure which can match with measurement errors is proposed, simulation result shows that the approach is feasible and available.
