On a novel PN-code pulse compression technique in a radar application: impacts of non-ideal system properties

In a new low-power short range radar system, a novel unbiased pulse compression algorithm is utilized. This algorithm shows an inherent perfect sidelobe suppression, thus avoiding the masking effect of small radar targets in the neighbourhood of very large ones. Three effects, distorting this desirable property, which occur in real, non-ideal systems, are analyzed in this paper. These effects are: shift of sampling time grid by fractions of the sampling period, signal offset, and signal saturation. Analytical results, simulations and measurements are presented and discussed; solutions to cope with these effects are described
