Improved Track Initiation for Bistatic Radar on Moving Platforms Using Coupled Position and Doppler Measurements

Traditional algorithms often fail to consider or inadequately utilize Doppler information during track initiation, leading to limited performance in this regard. Moreover, existing methods mainly focus on monostatic radar, neglecting the influence of platform motion and bistatic radar configurations on track initiation algorithms. In this paper, we propose a Doppler-aided track initiation algorithm for the bistatic radar on moving platforms. The proposed algorithm considers the coupling between target position measurements and Doppler measurements, making full use of Doppler information. Additionally, to avoid the significant computational burden brought by batch processing, we employ a sequential processing strategy for track initiation. Experimental results demonstrate that compared to the traditional track initiation algorithm, the proposed algorithm achieves a higher probability of correct track initiation and effectively suppresses the initiation of false tracks.
