Coherent integration technique is one of the most useful methods for the improvement of radar detection ability of a weak maneuvering target, whereas it would easily run into the range migration (RM) and Doppler frequency migration (DFM) effects resulting serious integration loss during the coherent accumulation period. In this paper, a new coherent integration method, known as the Radon-generalized...
This letter considers the coherent integration problem for a maneuvering target, involving range migration (RM) and Doppler frequency migration (DFM) within one coherent pulse interval. A new coherent integration method, known as Radon-Lv’s distribution (RLVD), is proposed. It can not only eliminate the RM effect via jointly searching in the target’s motion parameters space, but also remove the DFM...
Dynamic programming algorithm is an effective track before detect method. It recovers target trajectory at the same time as the detection is declared after processing several successive frames of measurement. This paper simulates the tracking accuracy of each frame of trajectory which is recovered from the maximum of merit function after executing dynamic programming. Several useful results for improving...
