Waveform analysis of transmissions of opportunity for passive radar

Abstract

Passive radar utilises electromagnetic radiation already present in the environment in order to detect targets and estimate target parameters. This paper presents a general investigation of the feasibility of this type of radar when the radiation utilised originates from common emitters of opportunity such as commercial radio and television broadcasts. It addresses the problem using waveform design theory and an assessment of the suitability of such transmissions of opportunity to the design of a matched radar receiver.
