Method for Direction Finding by Means of Monopulse Formation
First Claim
1. A method for direction finding by means of monopulse formation in a radar system with electronically controlled group antenna and analog beam shaping of sum and difference channels, the method comprising:
- performing a self-test of the antenna to identify failed receiving elements, and a result of the self-test goes directly into the monopulse formation and said test is thereby error corrected;
converting the result of the self-test into correction values (C, μ
x, μ
y) that, independently of the antenna viewing direction, are combined as follows with those from the sum channel signal (Σ
) and the difference channel signals (Δ
x,Δ
y) of the antenna;

Abstract
A method for direction finding by means of monopulse formation in a radar system with electronically controlled group antenna and analog beam shaping of sum and difference channels, a self-test of the antenna being carried out to identify failed receiving elements, and the result of the self-test going directly into the monopulse formation and the test thereby being error corrected. The result of the self-test is converted into correction values that, independently of the antenna viewing direction, are combined with those from the sum channel signal and the difference channel signals of the antenna.
