基于VTA的超视距雷达海面目标检测前跟踪算法
VTA-based algorithm for sea surface target TBD by OTHR
摘要
Abstract
A track-before-detect algorithm based on viterbi-like tracking algorithm is proposed with respect to the surface ship detection and tracking of weak targets for over-the-horizon radar. The echoes are processed in pulse compression and beam forming, with signal process is on doppler domain. For each range and azimuth cell,using adjacent cell's signal construct whitener for filtering the sea clutter. Then establish the generalized likelihood ratio of each cell by Bayesian estimation,as each element of matrix P. Finally, through the viterbi-like tracking algorithm, declare the detection result and output flight-path in the meantime. Simulation results show that this algorithm has effective detection of target exceed cell.关键词
