Detection Probability of WCDMA Based Cellular Radar System

Cellular radar is a kind of passive radar system. It uses the signal of a base station in a wireless communication system as an ´opportunity of illumination´ to detect a target. We must consider not only the detection criterion of radar system but also that of wireless system to constitute the concept of detection for cellular radar. It is obvious that the cellular radar system fails to obtain sufficient information of targets without guarantee of those two detection criterions. Therefore, we widely need to combine them and consider simultaneously. It is also important to measure how well a system can detect a target, so we define the detection probability. In this paper, we analyze necessity of two detection criterions, provide a novel definition of detection for the cellular radar and compute the detection probability.
