Mismatched filter for range sidelobes suppression of pseudo-noise signals

In Continuous Wave (CW) Radars, especially ones transmitting noise signals, the masking effect may cause weak echoes to be completely masked in the sidelobes of strong echo targets. In radars where the transmit and receive antennas are close to each other, the strongest signals are direct crosstalk...

Summary:In Continuous Wave (CW) Radars, especially ones transmitting noise signals, the masking effect may cause weak echoes to be completely masked in the sidelobes of strong echo targets. In radars where the transmit and receive antennas are close to each other, the strongest signals are direct crosstalk and close reflections. In this paper a novel mismatched filter is considered for suppressing the range sidelobes of the correlation function. Both simulations and measurement results are presented.
