This chapter continues the study of detection based on multiple observations begun in Chapter 10. The same basic approach is now applied to the detection of fluctuating incoherent pulse trains. Fluctuating pulse trains occur often in practice. When a radar target consists of several relatively strong reflecting surfaces displaced from one another by the order of a wavelength, the amplitude and phase of the composite radar echo are sensitive to the spatial orientation of the target. If the target has relative motion with respect to the radar, such as translation, pitch, yaw, tumble, it presents a time varying radar cross section.
