RADAR INTERFERENCE STUDY,
Abstract
The electrical signatures of a particular type of radar interference called angels were studied in detail during a three-year program using the radar facilities at Fort Dawes, Boston Harbor. The types studied were single angel, group angel, and misscellaneous. Based on the electrical signatures obtained during the early part of the program, circuits were developed and implemented to eliminate the single and group types from the FPS-8 (L-Band) MTI radar outputs. Cancellation experiments as well as the circuits used are discussed in detail. A physical model is presented to account for the single angel returns. Among other properties, the model accounts for the angel beamwidth relative to normal targets and the doppler shifted angel spectrum unaccompanied by any visible translation. The credibility of the theoretical model describing single angels is based on the experimental results. Experiments which could provide a more definitive confirmation of the theory are suggested.
