Abstract

Satellite recognition is increasingly important in modern wars, and relative techniques have been the hotspot to study. Due to the limitation of virtual load, the space-borne arrays are commonly chosen to be sparse ones. Thus, analysis of the direction finding ability to the ground emitters is particularly important. Estimation to ground emitters of space-borne sparse L-array is provided, and the simulation results obtained prove such arrays are good at high-precision direction finding.
