The applicability of certain optimization methods of operations research to the problem of controlling radio and radar interference by judicious assignments of equipment operating frequencies was investigated. Emphasis was placed on radar interference problems. A number of interference control methods applicable to radar and various optimization techniques which can be used in conjunction with these control methods are reviewed. A description is given of the search radar interference prediction program used to supply the input data for the optimization techniques developed. Four different optimization algorithms are presented in the form of computer programs written in the international computing language ALGOL 60. A field test involving radar frequency assignment was conducted. Interference levels were measured by interference pulse rates and subjective evaluation of PPI screen displays. A detailed account and analysis of the test procedures and results is given. It is concluded that in many situations in which radar congestion causes mutual interference problems, assignment of frequencies based on the techniques developed is feasible and desirable.
