Design Considerations For An Atmospheric Imaging Radar

This paper describes the design requirements, trade-offs and simulations involved with the design specifications of an Atmospheric Imaging Radar (AIR). Design constraints are discussed including size and portability. Radar details include the range of meteorological targets detectable, maximum range, and other criteria needed for the weather radar equation. A dual pulse repetition time waveform is used to improve the maximum unambiguous velocity and range. The trade-offs in volume, sensitivity and pulse integration are described in the radar design. Calculations are made and and initial plots showing at least 15 dBZ sensitivity at 10 km are shown for a radar that will image a cone 16.50 wide and 40 km long.
