Algorithm to Emulate RF Signal of Multiple Targets for Countermeasures Technique Assessment
Agency / Branch:
DOD / USAF
Matrix Research and Engineering will develop an optimal algorithm for producing the best possible emulation of multiple target signals using triad antenna array network. Phase I of the effort will develop and refine an initial algorithm and demonstrate it on a simple 6 element triad array. To minimize the expense of the hardware we will constrain ourselves to using only one triad per target emulated. The approach will use a least squares approach to compute the optimal setting of attenuators and phase shifters that result in the closest possible wavefront impinging on the aperture under test to the desired one based on the emulated target geometry. Various optimization schemes will be considered to minimize issues when a target transition between triad arrays. Scalability will also be addressed during Phase I. The algorithm will easily support the use of more than 3 antennas per target as well as scale to a greater number of targets emulated by a large array of networked triads. During Phase II the concept will be validated on larger triad arrays. Special attention will be taken to ensure ease of setup and use of the software during this phase of the program.
