FLIGHT International, 22 November 1962 ^W*^" • .."• . . How the Phantom H Records What the Radar Sees Early in the development of the Phantom n, McDonnell designed a Direct Radar Scope Camera (DRSC)* as part of the instrumentation necessary for armament control system evaluation. It was soon apparent that the low cost, low volume, re liability, simplicity, inflight reloading, recording capabilities and projector playback characteristics of this device made it ideal for crew training and evaluation. At the request of the U.S. Navy, McDonnell put the system into production and it is now standard equipment on Phantoms being delivered to the fleet. More recently, the McDonnell Direct Radar Scope Camera was spec ified for the F8U-2N and the F-110. The system includes a McDonnell developed KD-26A camera, periscope, and electronic control assembly. Mirrors and prisms are used to shape the periscope to installation requirements. A unique application of an optical principle eliminates glare and double images while allowing the observer to change scope intensity without reducing photo graphic quality. The KD-26A is a pulse operated 16 milli meter camera using standard 50 foot film magazine for inflight reloading. During radar search, the shutter is triggered at the end of each azimuth sweep. During tracking, the camera is pulse oper ated at 2-6 frames per second. Correlator lights are introduced to mark such events as lock-on, firing, snap-up and other incidents where a record is desired. The film can be quickly developed and projected for crew training and evaluation, main tenance trouble shooting or mission documentation. The McDonnell DRSC is presently being proposed for a number of all weather fighter air craft in addition to applications such as sonar, air traffic control, weather and navigational radar recording.
