The preceding chapters have devoted some detail to the fundamental aspects of radar: transmission/reception; antennas; waveforms; propagation; RCS; SNR; detection; and accuracy of measurement of range, velocity, and angular position. This chapter combines those fundamentals and considers the particular advantage of applying those techniques to the case of a rotating target, which leads us to the important domain of imaging radar.
