Research and implementation of dynamic simulation for QPSK signal

The theory of dynamic simulation for QPSK signal has been investigated. The second-order model is built to simulate the variation characteristics of distance and Doppler for QPSK signal. The dynamic simulation circuit for QPSK signal is designed based on acquisition and tracking module. The circuit realized associated simulation for distance and velocity. The result of test shows the circuit has high precision and satisfies the radar system's request.
