Research on target model and echeos spatial correlation of distributed radar

The spatial correlation of target echoes is important to jointly process signals received at each radar substation in distributed radar system. On the background of space surveillance with two independent monostatic radars, a three-dimensional cylinder target scattering model and echo signal model are built combined the orbital motion. The echoes spatial correlation is analysed and correlation coefficient which varies with the included angle between two radars and target is derived. The reasonableness of target scattering model and validity of theoretical analysis are proved via simulation examples.
