Abstract
In this article, a commercial low cost solution
for increasing DVB-T based passive radar (also referred to as
passive coherentlocation)robustnesswith respectto channel
allocation and range resolution, is designed. IDEPAR demonstrator is updated to include a new recording system in charge
of DVB-T channels reallocation. The use of commercial hardware introduces frequency mismatching between acquired
channels that compromises system operation. To face channel frequency alignment, fulfilling the requirements imposed
by the high Doppler resolution typical of passive radars,
a novel compensation algorithm is proposed, based on the
minimization of signal dispersion in the Cross-Ambiguity
Function domain. The well-known cyclic prefix van de Beek
method is used as reference. Results show an increase in target signal to interference ratio and detection performances,
as well as a reduction of clutter dispersion when the novel proposed algorithm is applied. The low cost solution is also
compared to a high performance one capable of acquiring a wide bandwidth of sparse DVB-T channels, and performing
channel reallocation by digital signal processing. Results show that both systems reached similar performances in terms
of range resolution and SNR improvement.
