    Abstract: This disclosure is directed to an extreme ultraviolet radiation photometer which includes a special type window and cathode suitable for permitting radiation to penetrate the window which reacts with the cathode to produce electrons which are attracted to the window and produces a current flow which is measured to represent the radiation detected.

    Abstract: Aircraft are provided with a beacon for generating predetermined repetitive signals and sensors capable of informing the pilot of the presence, direction and range of another approaching aircraft. The sensor units are comprised of at least three detector pairs positioned in three orthogonal axes which are responsive to and generate signals in accordance with the radiation received from the beacon of the approaching aircraft. Signal recognition means are coupled to the detectors for detecting the predetermined repetitive signals and discriminating against all other signals. Logic circuitry is provided for deriving signals indicative of azimuth, elevation and range of the signals from the approaching aircraft, and these signals may be utilized in a display means for providing a visual indication of the position of the approaching aircraft.
