Influence Factors Analysis of SAR-GMTI System Performance

Abstract:

Many factors impact on the performance of SAR-GMTI system. Besides of minimum detectable velocity (MDV), the performance of SAR-GMTI system is involved in probability of detection and probability of false alarm when considering the interference factors (such as thermal noise, phase drift and unbalance between channels, etc.) and the stationary clutter. These three features of SAR-GMTI system are related to the values of the number of looks, CNR, SCR, the radial velocity of moving targets and so on. However, there is no paper described how these factors impact on the performance of SAR-GMTI system systematically which will strongly support the study of improving detection performance. This paper analyses influence factors and provides a group of reasonable value of them for simulation.
