Radar track-before-detect algorithm of dim target based on track test

This paper proposes a track test-based track-before-detect algorithm for radar target detection. Track test is used to estimate the target motion model. The implementation of this scheme on the search tracks and the detection strategy on the energy accumulation values of tested tracks are presented. Simulation results show the proposed algorithm have better detection performance and tracking performance, compared with the dynamic programming-based track-before-detect algorithm.
