Millimetre-wave radars in targeting and data linking operations

Millimetre-wave (W-band=75-110 GHz) radars are poised to form an important component of autonomous vehicle operations because high frequency systems are able to provide the conformal miniaturized solutions necessary for many robotic applications. A serial programmable integrated radar threat simulator (SPIRTS) that transmits 95 GHz centred emissions for investigating air-to-surface target threats has been developed and the performance of this unit in a targeting role is projected. Targeting operations at W-band are compared with those at lower K_a and X band frequencies. The upsides and downsides of W-band operation in clutter generation and in multi-path signal fading, important for future high frequency communication links, are highlighted. Clear air propagation effects for datalinking operations are also discussed for W band emissions.
