Abstract :
The low pulse repetition frequency (PRF) radars are used for searching and precise target tracking primarily. They obtain targetpsilas accurate range as the primary measured parameter, but there is ambiguity in radial velocity measurement. In this paper, unambiguous targetpsilas radial velocity values can be obtained in low PRF radars through the digital intermediate frequency locked loop (DIFLL) and spectrum peak search (SPS). The simulation results verify the availability and high practicable value of the method.
