In this paper we present a family of low-complexity and power-efficient Track-Before-Detect (TBD) procedures for early detection of moving targets from airborne radars. Upon a sectorization of the coverage area, the received echoes are jointly processed in both the azimuthrange- doppler domain and the time domain. The proposed tracking algorithm carefully exploits the physically admissible target transitions among successive illuminations and the finite width of the antenna beam in order to efficiently collect all the energy back-scattered during the Time-on-Target (TOT). The Constant-False-Alarm-Rate (CFAR) constraint is also included in the proposed procedures as well as the possibility of working with quantized data.

Abstract
In this paper we present a family of low-complexity and power-efficient Track-Before-Detect (TBD) procedures for early detection of moving targets from airborne radars. Upon a sectorization of the coverage area, the received echoes are jointly processed in both the azimuthrange- doppler domain and the time domain. The proposed tracking algorithm carefully exploits the physically admissible target transitions among successive illuminations and the finite width of the antenna beam in order to efficiently collect all the energy back-scattered during the Time-on-Target (TOT). The Constant-False-Alarm-Rate (CFAR) constraint is also included in the proposed procedures as well as the possibility of working with quantized data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
