DVB-T interference cancellation in radar signal processing
Paper i proceeding, 2014
In this paper, a novel filter for cancellation of DVB-T
interference in low-frequency synthetic aperture radar systems
is presented. The filter relies on using the pilots in the DVB-T
signal to estimate the communications channel between the
broadcast antenna and the flying radar system. Then, by decoding
and re-coding the interference signal, it can be subtracted from
the combined radar and TV signal. Simulation results indicate
good performance in relevant signal-to-interference ratios.
