New approach to 2d Medium PRF ambiguity resolution with application to air surveillance radar

This paper illustrates a new algorithm for noncoherent integration and ambiguity resolution in medium PRF wave-forms. Range and Doppler ambiguity resolution is one of the main issues in Medium PRF radars [1,2,3]; it will be shown that the proposed algorithm provides range and Doppler ambiguities resolution as an inherent feature while maximizing detection probability with respect to conventional binary integration. The algorithm is described and tested by means of a numerical examples, in which non ideal radar accuracies and target cell migration are considered and managed with a proper clustering technique. The resulting design of the algorithm shows high robustness to the aforementioned sources of error affecting radar measurements.
