Detection models for radar ground targets

Abstract

Models are presented for ground targets detected by a high resolution airborne radar. Results of the modeling of some simple scatterers are presented, along with chi-square approximations to these models. Simple stabilized targets are modeled with 0.6 to 0.8 duo degrees of freedom (K). Targets with unknown rotation are modeled with K of about 0.3. The effect of cell straddling is quantified and found to be about 1.3 dB loss for one dimension and 2.8 dB loss for two dimensions. The effect of these models on detection performance is discussed.<>
