Antenna placement optimization on tactical vehicles using a hybrid method: modeling and simulation and hardware in the loop Presentation by: Erick Ortiz, Tim Garner and George Palafox

A hybrid method of antenna modeling and simulation, or M&S, and hardware in the loop, or HWIL, testing would enable cost and time saving implementation of antenna placement on tactical vehicles. A hybrid method of M&S and HWIL offers a number of advantages over traditional testing alone; it allows antenna placement to be evaluated before the actual vehicle is integrated; can reduce integration cost, schedule, and performance risk; enable simultaneous decision-making; and evaluation of more antenna placements.

Model of a tactical vehicle with Whip Antennas

Features: Antenna Modeling and Simulation o Can be used to predict isolation between antennas o On-vehicle antenna M&S is done in a few basic steps Create antenna model Create vehicle model Combine antenna and vehicle models Excite active antenna and compute antenna isolation Hardware in the loop: o HWIL testing allows the amount of interference between radios to be determined in the laboratory o It does not require access to a test vehicle or a large test range o HWIL testing also provides the ability of viewing the transmission signals at any connection point using a Spectrum Analyzer o HWIL is cheaper, shorter and safer than traditional testing
