Abstract:
The study of classification characteristics for small aircrafts is the one of major problems required the priority solutions to make passive radar-s systems. The echo-s classification of the small moving objects based on its amplitude characteristics and range images is difficult. It-s informed that two groups of classification characteristics based on analysis of small and large aircraft-s echoes and mathematics - simulation method are studied. The first group of characteristics uses the features of fine structure for the Doppler major echo from the aircraft body-s translation motion. The second group is the unique characteristics of the micro-Doppler echo-s structure by the propeller-s modulation for the each object-s type. It-s shown that the exploitation of two groups of classification characteristics and two-polarization receiver can highly increase the ef-fectiveness of the moving object-s classification for a wide range of distances.
