High fidelity robust testing of modern receivers demands highly accurate signal generation that is commensurate with complex environmental conditions. Demands of the modern digital receivers can only be met with a flexible signal generation scheme that will faithfully reproduce subtle features of the signal wavefront. CRS has pioneered software based complex signal simulators and receivers for navigation, communication and radar applications. We propose to extend the software based real time wavefront simulation capabilities for flexible jamming signals. The simulator will be able to generate live RF signals for different bands and will provide faithful reproduction of all aspects of signal generation (waveform, code, carrier, antenna, power, source motions, orientation, etc.), propagation (attenuation, dispersion, scattering, and multipath, etc.) and receiver configuration (antennas, receiver dynamics etc.). A variety of signal waveforms (radar, communication, jammer, navigation, etc.) will be built in and additional waveforms can be added as needed. High fidelity and precision will be maintained throughout the system (accuracy of 1 mm is achieved) and special care in terms of analog portions particularly in those involving code and phase relationships will be maintained. During Phase I we shall address the issues, define the requirements, perform the design, and provide end-to-end simulation of the entire system that would allow us to obtain the performance metrics and help engineering design during Phase II. A hardware demonstration (using available hardware) will also be provided during Phase I to demonstrate the feasibility of software based implementation approach.
