Abstract

Abstract: The drawbacks of traditional Hough transform (THT) track initiation algorithm for using binary integration are discussed, and a new multi-radar track initiation algorithm is presented which makes use of the probability distribution of the measurements for integration. First, the observation space is divided into uniform-sized grids, and then the probability of the radar measurements falling within each grid is calculated, which is used for Hough accumulation. Compared with traditional methods, this method exhibits an improved performance in accuracy and robustness, and is suitable for radars with different precision requirements. Simulation results demonstrate the effectiveness of the algorithm.
