Waveform Agile, Low-cost Multi-function Radio Frequency ISR in Contested Environment

ABSTRACT:The Goleta Star team proposes to develop innovative waveforms and exploitation algorithms for concurrent synthetic aperture radar (SAR) and ground moving target indication (GMTI) in contested A2AD environments. In Phase I we will evolve the detailed design of the radar waveforms and processing such that in Phase 2 we can demonstrate the waveforms and processing in a flyable prototype of the system enabling the collection of relevant SAR GMTI data. We will design transmit signals and exploitation algorithms for simultaneous SAR and GMTI processing. We will explore Doppler-tolerant waveforms like Linear Frequency Modulated (LFM) and others. We will develop and test these with the help of simulation and hardware. Using innovative approaches the team will develop signature exploitation concepts for concurrent SAR and GMTI for multiple moving and stationary targets detection, geolocation, and tracking. Goleta Star has been designing and flite testing small MMW band SAR GMTI radars for over ten years. The team has all the capability necessary to rapidly design, develop, build, flite test and produce the desired radar waveforms and processing with a fast track path to commercialization.BENEFIT:The key benefits to the warfighters will be: (a) transmit signals can hide in adversaries environment but enable ISR objectives, (b) solve the joint SAR and GMTI problem without complexities associated with reconfiguring the radar systems for SAR or GMTI mode, and (c) make this affordable for transition to the critical end users.
