Extensive Monte Carlo simulations for performance comparison of three non-coherent integrations using Log-t-CFAR detection against Weibull clutter

Due to new generation digital processors, the problem of large processing time required by complex detectors can be easily overcome. To this effect, we propose to extend the use of a single pulse log-t Constant False Alarm Rate (CFAR) detector in Weibull background to noncoherent multiple pulse processing. The echoed pulses are treated within the same receiver in three different ways, namely; the conventional integration detector (CI-CFARD), the non-conventional integration detector (NCI-CFARD) and the binary integration detector (BI-CFARD). The detection performances are evaluated through Monte Carlo simulations and show that the non-conventional integration technique yields the lowest CFAR compared with the other non-coherent integration techniques.
