A new concept in commercial airborne weather radars was developed for the turbo and pure jet-powered general-aviation aircraft. This radar presents a steady, nonfading weather or ground picture, without using the conventional direct-view storage tube, by utilizing digital processing techniques. Careful treatment of the radar design parameters allows 200 n. mile range operation while only requiring a few amperes of 28 V d-c from the aircraft power bus. These techniques are being applied to a family of radar systems.
