Abstract

PURPOSE:To keep the target and prevent it from being lost covering a wide range by controlling the pulse repeated frequency (PRF) in proper combination. CONSTITUTION:The command from the system control 2 controls the pulse repeated frequency of the pulse modulator 3. Two combinations of PRF's prepared in large number are used alternately. This prevents the receiving of the incoming signal when the radar transmits the signal thereby minimizing the possibility of the target being lost covering a wide range.
