Slide window algorithm is a searching algorithm. Its operation efficiency in real time is an important indication. The slide window algorithm used for resolving the ambiguity of radar target is analyzed. This paper introduces a parallel realization of multi slide window algorithm on two TMS320C5402 chips. It is used for resolving ambiguity in range and velocity in some PD radar system. With the HPI, the three ply slide window algorithm has been realized in azimuth, range and velocity. The detailed hardware scheme, software flow charts and some methods are used to improve computation efficiency.
