TOA data association based on peak detection of reconnaissance region

To solve the problem that the permutation and combination in the traditional data association algorithms result in a high computational cost, this paper proposed a novel TOA data association algorithm based on the peak detection of reconnaissance region. Firstly, some samples of the TOA curves can be obtained by azimuth searching, and then the data association problem can be transformed into a 2-dimensional detection problem by blurring and adding the curves. The simulation results show that the proposed algorithm can improve the computational efficiency with hardly reduce of the correct association probabilities, implying good application prospect.
