An improved IPCP detector of UWB radar signals based on adaptive searching window

The research on detection of range-extended targets has been a focus of UWB radars. The paper introduces weighted accumulation and adaptive searching to the IPCP detection, and theoretical value of detection threshold is derived in detail. Related experiment and simulation confirm that weighted accumulation increases SNR effectively and adaptive searching basically eliminates the negative effects on detection performance caused by unknown extended range of the target echoes, which guarantees the reliability and stability in practical application.
