Abstract: The angle resolving method of two narrow band Gaussian noise jammers for the passive monopulse seeker is presented. In the case of one jammer within the main beam, the average angle of arrival given by the seeker points in the direction of the jammer. In the case of two jamers within the main beam, the average angle of arrival points at the power centroid. One or two jammers within the main beam can be distinguished by the complex angle. By using the complex angle and clustering analysis, an angle resolving method of two jammers is presented. The method is verified with the results of digital computer simulation.
