Waveform Analysis of Transmitters of Opportunity for Passive Radar

摘要

This report investigates the suitability of a number of broadcast band transmitters of opportunity for a passive radar. Specifically, this report reviews the design of active radar waveforms, measures emissions for representative transmitters of opportunity, and assesses the suitability of these signals for various types of radar observation. This report shows that it is indeed possible to construct the suggested passive radar, although performance is limited and depends largely on other parameters, such as receiver bandwidth, antenna pattern and observation time.
