Robust Uniqueness Conditions for Resolving Range and Doppler Ambiguity and Determination of the Range of Medium PRF

The radars that use medium PRF, have either range ambiguity or Doppler ambiguity, but these ambiguities can be resolved with selecting a PRF set. Avoiding ghost targets detection and minimizing blind zones are two important points that should be considered in targets detection. Then, using this set, coincident algorithm and clustering the closely detected points, we resolve ambiguity and detect the targets. After that, to decrease ghost target detection, deghosting algorithm is used. In this paper, a new definition of uniqueness condition is presented to be robust against errors when clustering is employed. Also, it is shown that the medium PRF range depends on the maximum range and Doppler as well as range bin and Doppler bin.
