ABSTRACT
This chapter presents the concept of a moving target indicator and pulse Doppler radars. Target echoes of a moving target may be extracted from clutter by taking advantage of the difference between target and clutter spectrum. This is due to the usually larger Doppler effects of the moving target. Moving target detection can be enhanced by two common methods: moving target indicator (MTI) filters and using pulse Doppler waveforms. In this chapter we discuss how delay line cancelers can be used to mitigate the impact of clutter within the radar signal processor. Pulse repetition frequency staggering is analyzed in the context of blind speeds and in the context of resolving range and Doppler ambiguities. Finally, pulsed Doppler radars are briefly analyzed. The use of pulse Doppler waveforms is more complicated but provides additional information, such as the radial velocity of the target and an indication if the target is approaching or receding.
