An overview of an illuminator of opportunity passive radar research project and its signal processing research directions

In this paper, an overview of an Illuminator Of Opportunity (IOO) passive radar research project being conducted at DSTO is presented, with a specific focus on the signal processing research directions that are being investigated. The overview provides a discussion on the selection of transmitters as well as a description of the multi-channel receiver. The signal processing research direction discussion will cover such topics as: the development of a computationally efficient approximation to the 2D Woodward cross-ambiguity function; improving the cross-ambiguity SNR by exploiting the transmitted waveformʼs inbuilt Forward Error Correction; as well as signal processing means for suppressing the LOS and strong clutter interference.
