From: Coherent CFAR detection in compound Gaussian clutter with inverse gamma texture
HH-polarisation examples of performance of CFAR (17), relative to Ingara data-based clutter parameter estimates. The left subplot is for the case where N=30,ρ=0.5 and probability of false alarm is 10−6. Both texture parameters have been overestimated by a factor of 5. Despite this large error, the new CFAR performs very well and certainly improves on the NMF. The right subplot is for N=40,ρ=0.9 and a false alarm probability of 10−7. The clutter parameter α is overestimated by double, while there is a 20% error in the estimation of β. As before, we observe that the CFAR (17) has very good performance.
