摘要

To solve the problem that the algorithm's slow convergence, or the lower computational efficiency, which caused by the uncertainty of the search accuracy in Doppler frequency shift space, an improved target motion analysis algorithm of bearing-line Doppler frequency shift is introduced. The filter equation is transformed from the nonlinear field to the simple linear form field. When the Doppler frequency is matched, a new optimize search matching algorithm is introduced, and the best estimate problem of the search element's objective function is transformed into a multi-peak and nonlinear optimization problem. Experiments show that the algorithm can decrease the time and space complexity of the algorithm, improve the computational efficiency and convergence precision, and reduce the tracking time.
