Upgrading armored vehicle sensor systems

Successful sensor modifications or upgrades of existing armored military vehicles call for extensive information of the desired operational environment, host vehicle and weapon system characteristics, and sensor performance limitations. Radar systems operating in the higher microwave or millimeter wave bands seem to be an attractive choice in terms of tracking capabilities and operation in poor visibility. Efficient mechatronic arrangements are needed for the stabilization of the pedestal at least down to 0.1/spl deg/ level if full specifications must be met also during platform motion or weapon launches. No ultimate parameters have been observed, until now, that would totally preclude the usage of such a short-range radar also at zero antenna elevation in typical sub-arctic scenery. The fluent throughput of the entire fleet upgrading task and future maintainability must be evaluated parallel to the acute technological challenges and user requirements.
