ABSTRACT: The passive radar is a hot research topic.
A multi-channel wideband passive radar experimental system is designed and the
digital television terrestrial broadcasting (DTTB) signal is chosen to carry
out the target detection experiment of civil aviation aircraft. The
polarization and spatial filtering methods are used to solve the strong direct
path interference suppression problems brought by the receiving system
location; combined with the characteristics of DTTB signal, the block length
selection interval in the block batch processing method for range-Doppler
images calculation is given; the clutter suppression performance is compared
through the experimental data receiving from different bistatic polarization
channels, the conclusion is different from the monostatic radar and it can
guide the passive radar experiment.
