Pulse Doppler Radar by Clive Alabaster (2012) — a practical guide to airborne pulse-Doppler theory, FFT-based processing, clutter mitigation, system design and case studies. The desired performance index is a probability of detection (Pd) of 0. 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. Radars have average powers from a few milliwatts to as much as one or more megawatts, depending on the application.

Important distinguishing feature to other radar method is the necessary time control of all processes inside the pulse radar. Analyze Doppler effects and implement and understand MTI and pulse-Doppler processing strategies. A pulse radar system is a type of radar system that uses short pulses of radio frequency (RF) energy to determine the range, velocity, and/or angle of objects. The average power, rather than the peak power, is the measure of the capability of a radar system. That is to say, the waves are interrupted for a period of time so that the wave can reach a reflecting target and a portion of the energy can return to the same antenna before the next burst of waves is transmitted. These light pulses—combined with other data recorded by the airborne system — generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. The receiver is almost always of the super-heterodyne type, as most radio receivers are; the (second) detection comes after frequency conversion processes.
