Resolution of range and velocity ambiguity for a medium pulse Doppler radar

In medium pulse repetition frequency (MPRF) radars, ambiguities exist both in range and Doppler measurements. Some efficient techniques have been established to resolve the range and velocity ambiguity of the target using multiple PRFs. In this paper, a simple algorithm is proposed to resolve both range and velocity ambiguity based on residue arithmetic. This algorithm makes out the unambiguous result by using a residue look-up table. The particular problem about filter bandwidth unitary in frequency is settled and assessed with another algorithm. An example for the generation of the residue look-up table is presented to resolve range ambiguity.
