Joint RADAR waveform design for networked ISR systems

In this paper we describe methodologies for joint design and exploitation of heterogeneous RF Intelligence Surveillance Reconnaissance (ISR) sensor networks. In this work, we provide an algorithm that simultaneously optimizes a waveform set that overtly incorporates the aspect variant nature of the target and clutter signatures along with the mutual interference of the waveforms. The basis of the optimization is a maximization of the composite signal-to-interference-plus-noise ratio. The work reported here generalizes the single optimal waveform design approach of Pillai et. al. to the case of J simultaneous waveforms. Knowledge of the target spectral support for each aspect is assumed and the waveform set is jointly optimized. Simulation results are given that show the waveform characteristics and the increase in signal-to-interference-plus-noise ratio over sets of chirp waveforms and independently optimized waveforms.
