Joint Optimization of Detection and Tracking in Adaptive Radar Systems - Advances in Heuristic Signal Processing and Applications - page 112

Fig. 6.1 Block diagram of a conventional tracking system with a decoupled feed-forward structure. This block diagram is rather generic in the sense that the
sensor can be either an active one such as an active sonar, radar, or ladar (laser detection and ranging), or a passive one such as a passive sonar, electro-optical
(EO) or infrared (IR) sensor. In the active case, the energy flow in the channel is bidirectional where the energy is transmitted towards the target via a transmitter
(Tx) and the returned echo is received with a receiver (Rx). The type of energy can be either electromagnetic as in the case of a radar, ladar, EO and IR sensors,
or acoustic as in the case of an active/passive sonar. The focus of the chapter, the adaptive detection feedback path , is to a large extend independent of the sensor
type used except when a specific detector is used as an example. However, to be more specific, the presentation in this chapter is in the context of a radar sensor
