How does amplitude based monopulse work in wideband frequency range?

04 April 2016 1 3K Report

In amplitude based monopulse method, you use the sum and difference antenna patterns for direction finding of the target.

However, if the frequency range is wide, such as the whole X-band (8-12 GHz), how do you obtain the sum and difference patterns?

Since the antenna pattern changes with frequency, do you have to measure the sum-difference patterns for each frequency separately?

Andrea Piroddi

yes, you have to measure the sum-difference patterns for each portion of the bandwidth. You can try to use Evolutionary Algorithms to reduce the computational effort.

best regards
