Relief recovery by synthetic aperture radar that parasites over TV broadcasting signals

Nowadays digital relief recovery is one of the most top-priority areas of modern Earth remote probing system applications, where synthetic aperture radar (SAR) is possible and effective techniques, and so-called “parasitic systems” are the most interesting among SARs for described purposes, which utilize radio signal unrelated to radio systems as a probing signal. This work is concerned with problem of digital relief recovery by using SAR that “parasites” over TV broadcasting signals. Digital model development is strongly complicated process especially under low angles of incidence and signal interference occurring due to compact design. We present of some results for SAR simulation that parasite over TV broadcasting signals. Here radar imaging is considered with fixed transmitter and mobile dual-channel receiver. Simulation of algorithms for digital relief recovery by radar interferometry was performed by real TV signals detected in “direct” channel. Reflected signals and interference image were simulated. We analyzed ability of height recovery under noised reflected signal. Simulation results demonstrated potentiality of proposed technology application on practice.
