Noncooperative Radar Illuminator Based Bistatic Receiving System

Abstract

Target detection and tracking systems using illuminators of opportunity have received significant interest in the past few years. The passive bistatic radar system under investigation in this paper exploits non-cooperative navigation radar. In order to provide useful surveillance or cueing information, certain data must be collected from the direct-path signal of the illuminator. Detection of aircraft is an important step to demonstrate its potential in remotely surveillance. The PBR illustrates the detection of civil passenger aircrafts in the airspace by receiving a bistatic return when they are illuminated from non-cooperative emitters. The results show that target detections have been achieved from real data. “Air-truth” data obtained by a Mode S ADS-B receiver is used to verify the results of this bistatic system.
