<p>PROBLEM TO BE SOLVED: To solve such problems that when there is a setting error in a Rotman lens, the accuracy of an estimated azimuth value is lowered, and although the number of output terminals of the Rotman lens is increased to improve the accuracy of azimuth estimation, it is necessary to increase the number of processing circuits as well, resulting in increase in the size and cost of the device of an azimuth detector. SOLUTION: This azimuth detector is provided with the Rotman lens identification device 8 for previously identifying the characteristic of the Rotman lens 3 using test data, and an azimuth calculating device 7 for calculating and estimating the optimum azimuth to the incoming wave among the outputs obtained from the plurality of output terminals 4A, 4B, 4N of the Rotman lens 3 according to the identification result.</p> |
