Abstract:

This report describes the flight tests performed for a radiometric bomb guidance system developed by Martin-Marietta Corp., Orlando, Florida. The preliminary system evaluations prior to the joint USAF-Navy flight tests at Santa Ana, California are discussed and the results of these initial tests are presented. The modification of the frequency-scanned radiometric bomb guidance system is then described. For this modified system the dual-beam frequency- scanned radiometer the development of the circuitry for a stairstep mode and a ramp mode of operation is discussed. A dual-beam frequency-scanned antenna network employing RG-52U slotted waveguide is given, and the results from tower tests of the system are presented. Finally, an alternate system, a modified dual-beam frequency-scanned radiometer, is described. The range gate circuitry and a frequency-mechanically-scanned antenna are described. Preliminary tower test results are then given.
