BROAD-BAND MONO-PULSE PHASE COMPARATOR

摘要

PURPOSE: A wideband mono pulse phase comparator is provided to enhance the accuracy of detection about a target in a radar system. CONSTITUTION: A branch line combining unit(60) outputs a mono pulse signal inputted by a first input port to a first output port and a second output port and outputs the mono pulse signal inputted by the second input port to the first output port and the second output port. A phase delay line(20) delays the phase of the mono pulse signal outputted to the first output port in 90 degrees. A differential phase delay line(70) recompenses the phase difference of the mono pulse signal outputted from the second output port and the mono pulse signal which is phase-delayed in 90 degrees by the phase delay line.
