Adaptive target tracking is one of the ways to save radar resources.An adaptive target tracking algorithm based on phased-array radar was researched in this paper.Traditional continuous sampling algorithm was described,which limited the sampling period by setting upper and lower bounds.An improved discrete sampling algorithm was given based on the continuous sampling algorithm,which set a set of discrete sampled values by comparing the residuals and measurement error.The improved algorithm reduced the computational and the tracking error.Monte Carlo simulation comparisons between the two kinds of adaptive sampling algorithms and fixed-period sampling algorithm were carried out based on IMM.The result shows that the two kinds of adaptive sampling algorithms have greatly reduced the sampling rate,and the discrete adaptive sampling algorithm has relatively good tracking performance.
