Compact Optimized Multimode Simulator Utilizing a Novel Electronically Steerable Antenna

WaveBand's solution for RF target glint signature generation as it applies to a compact range multi-mode hardware-in-the-loop (HWIL) simulator is based on the following three innovations: a phase/amplitude controlled electronically steerable module (ESM);wide angular view adjustable MMW optics; and a trichroic beamcombiner, for the alternative geometry of RF folding/IR transparent window.The combination of these novel, but verified, techniques allows WaveBand to optimize the compact range design and fabrication, both in terms of the overall range footprint and of its cost and complexity. WaveBand's solution overcomes inherent compactrange limitations caused by the fact that the far-field antenna requirements cannot be satisfied.The application of the proposed innovations will enable: 10 MHz angle of arrival update rate for the composite signal synchronized with the seeker waveform; multiple target simulation; 1.0 GHz instantaneous bandwidth; +/- 1.5 mrad accuracy of beampointing; dynamically adjustable beamwidth compatible with the seeker under the test (SUT); multi-mode operation by combining IR and SAL signals with MMW on SUT. Phase I will demonstrate experimentally 1-D functionality of the proposed compact simulatorusing WaveBand's scanning antenna as SUT. The proposed range will benefit MMW radar development for automotive, aviation, security, railroads and marine markets as a compact and affordable test bed.
