Fast radar detection algorithm based on two‐dimensional non‐uniform trilinear autocorrelation function for manoeuvring target with jerk motion

This letter presents a fast detection algorithm based on a two‐dimensional non‐uniform trilinear autocorrelation function for the manoeuvring target with jerk motion. In the proposed algorithm, the echoes’ energy can be integrated into peaks in a three‐dimensional parameter space coherently, and the range migration and Doppler frequency migration can be compensated simultaneously. Compared with other representative detection algorithms, this proposed algorithm can achieve a good balance between the computational complexity and detection performance.
