Doppler processing refers to the use of Doppler shift information to achieve one or both of two goals. The first is to enable detection of targets in environments where clutter is the dominant interference. The second is to measure Doppler shift, and thus radial velocity, of targets. In this chapter, two general classes of Doppler processing will be discussed: moving target indication (MTI) and pulse-Doppler processing. MTI processing addresses the first goal; pulse-Doppler processing addresses both.
