ABSTRACT
This chapter shows how to estimate ultra-wideband radar performance. The same performance prediction principles apply to all radar systems. Returned radar signals in noise are neither deterministic periodic nor deterministic transient, but, rather, are continuing messages in noise which do not approach zero in any sense as time tends to infinity. One of the major advantages of time domain (TD) radars is their ability to obtain a large amount of target data, some of which will be aspect dependent. The TD approach to surveillance brings us the problems associated with well-defined temporal and spatial initial conditions. The ability of TD systems to characterize a target far exceeds that of frequency domain systems, but only if the correct receiver-processor design philosophy is adopted. The importance of integration in pulling weak echos of distant targets out of the noise is important for both FD and TD systems.
