Implementation of Unambiguous Estimation of Angular Coordinates in Monopulse Radars Using an Additional Antenna

A technique is proposed that provides the setting of the working angular range of the direction finding characteristic. It is based on the application of a weighted comparison of signals coming through the total and compensation channels of reception in the onboard radar station. For various types of antennas used as a compensation channel, the implementation of the evaluation of the comparison coefficient is proposed, which is effective for obtaining an unambiguous estimate of the angular direction in antennas with electronic beam scanning. The results of the work can be used to improve the accuracy of forecasting the flight routes of other air objects and reduce the likelihood of a collision in the air.
