  • A practical mathematic model of modulation characteristics of Propeller Aircraft (PA) returns in the Low-Resolution Radars (LRR) is proposed in the paper, based on configuration of PA and characteristics of LRR. The model is analyzed and simulated with actual parameters of PA and LRR. Then, modulation characteristics of actual returns from PA in the LRR are analyzed, and modulation limitations from LRR are discussed. Finally, a comparison between the analyzed and simulated results shows the agreement of theoretical model with practical application. Mathematics relationship between modulation of LRR and target configuration is established.
