Passive radars utilizing pulse radars as illuminators of opportunity

Abstract

Much of the current research on passive radar is focused on the exploitation of commercial emitters providing continues wave illumination of surveillance area. It is also possible to exploit another kind of the illuminator - pulse surveillance radar. This paper presents the concept of passive radar exploiting the mechanically scanned foe and friend radars for providing extended radar surveillance. The paper presents theoretical analyses of coverage of single passive radar, the set of single active radars and a number of passive radars for different data fusion schemata. The results of real-life experiments conducted are also presented.
