Capability of Bistatic Radar Systems to Solve the Problem of Detection of Potentially Hazardous Celestial Objects

We analyze the capabilities of bistatic multipositional facilities with correlation signal processing for the purposes of enhancing significantly the efficiency of radar systems in detecting celestial objects which are potentially hazardous for the Earth, specifically, asteroids, comets, and large fragments of space debris. In particular, we consider radar systems using the forward scatter radar method, which is based on a significant increase in the bistatic efficient reflective area of the target independently of its shape and material in the case of forward scattering of the probing signal. The possibility to use natural radio sources as probing emitters is considered. The efficiency of two variants of ground-based space radar for both detection of celestial objects and monitoring of space hazards is estimated for further promising research developments.
