Abstract: A method including providing a replica of a signal emitted by an on-board radar, receiving by a radar detector a signal, the received signal being the sum of a first signal depending on the signal emitted by the on-board radar and a second signal independent of the signal emitted by the on-board radar, the first signal being able to be represented by a linear combination of elementary signals each having an amplitude coefficient and a delay relative to the signal emitted by the on-board radar, processing the received signal, determining the amplitude coefficients and the delays of the elementary signals of the first signal relative to the signal emitted by the on-board radar, from the provided replica and the processed received signal, and eliminating, in the processed received signal, the first signal to obtain the second signal, from the provided replica.

Abstract: A system and method of radar location comprises radar signal emission means, an emitted pulse of duration T1 and index i starting at instant T2(i); means receiving reflected radar signals; means determining correlation between reconstruction of an emitted pulse and signal received during the time interval between T2(i)+2*T1 and T2(i+1). The means determining a correlation can reconstruct a set, of at least one truncated pulse j of duration T3(j), less than T1, corresponding to the final part of said emitted pulse, said truncated pulses having increasing respective durations, determining at least one first correlated signal j by correlation of said truncated pulse j and signal received during time interval between T2(i)+T1 and T2(i)+T1+T3(j) and determining a second signal, based on first correlated signals j, by copying the time interval, of said correlated signal j, between T2(i)+T1+T3(j) and T2(i)+T1+T3(j+1), onto the time interval, of said second signal, between T2(i)+T1+T3(j) and T2(i)+T1+T3(j+1).
