Fault-tolerant PRF design for the resolution of velocity ambiguities

For low PRF radar, it usually needed to resolve velocity ambiguity. Almost all ambiguity solutions might get the wrong result when the velocity of the target changed between the stagger frames. Residues' difference look-up table method was introduced, and the reason why the method made mistake was analyzed. Aim at Residues' difference look-up table method, how the PRF stagger design effects on the performance of the method is researched, the rule of the PRF stagger design are given, which assure the method get the best performance. Simulation results show the efficiency of the rule.
