A radar system probes its environment with specially designed waveforms to identify and characterize targets of interest. Pulse Doppler radars are half duplex, meaning that they either transmit or receive, which results in high isolation between the transmitter and receiver, thus increasing the dynamic range of the receiver and the range detection of the radar. 1; the specifications are listed in Table 1. A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity.
