Pulse Doppler Radar

Abstract

This chapter provides an overview of pulse Doppler radar. In pulse Doppler radar, the range is estimated by binning the returns of the individual pulses by their time of arrival, which is proportional to the range. The Doppler processing is done by coherently measuring the phase shifts across many pulses. In this way, both range and velocity of targets can be determined. In addition, moving targets can be easily detected against a nonmoving background clutter. Fast Fourier transforms are used for both range and Doppler processing. The rate of pulses, or pulse repetition frequency, is an important parameter. Aliasing can occur in radar systems, similar to sampled signals. These concepts are all covered in this ...
