Abstract

In this work we compared the characteristics of the potential accuracy of measurements of angular coordinates for the three and four-channel monopulse direction-finding phase-phase sensitive elements with semi-arbitrary location of the receiving points on the ellipse in the plane of equal phases, which are in optimal maximum likelihood. Criterion it is shown that for low signal to noise ratio, three-channel sensor element has up to two times greater the potential accuracy of measurements of angular coordinates of location of the object.
