Zhu Run · Digital Communication · 2010
This paper discusses a moving targets detection method by utilizing CDMA pilot signals.According to the good detection performance of pilot signals,the scheme abstracting information about the appearing objects by long-time accumulation of coherent processing the real-time data in time-frequency domain was adopted.An experimental system based on a single receiver was proposed,and the Doppler frequency and distance detection of moving targets were accomplished by this system.The experimental results demonstrate that the scheme by utilizing CDMA signal for passive detection is feasible.
