Abstract : TWO METHODS ARE GIVEN FOR ANALYZING DATA OBTAINED FROM THE RADAR COORDINATE SYSTEM. Method I gives a functional relation between a coordinate difference of the two targets and their separation, and is given for theoretical interest, and because it provides a convenient independent check on the information obtained from Method II. The second method gives a procedure for obtaining complete information from the data furnished by a single radar array. The system for processing the data from the output of the receivers, particularly the techniques for comparing the phase differences, are discussed in detail. A series of experiments, designed to check out the system performance are discussed. Modifications made to the radar receiving system are described (Author)
