Novel Diverse Waveforms

Use of an interferometer along with a host radar is proposed for simultaneously achieving coherent reference denial and embedded communications. To prevent self-jamming, spatial orthogonality is achieved between the interferometer antenna pattern and main beam of the host radar. Costas and orthogonal frequency division multiplexing (OFDM) signals are suggested for the host radar and interferometer, respectively. Effectiveness of the interferometer masking signal on a non-cooperative bistatic radar is discussed.Air Force Research Lab Rome NY Sensorsdirectorate is the author of 'Novel Diverse Waveforms' with ISBN 9781423527855 and ISBN 1423527852.
