Digital mono-pulse method in cylindrical antenna
The article presents a method designed to improve the accuracy of cylindrical antenna
multi-beam sonar performance. The method is based on the mono-pulse method used in radars
and sonars. It provides good bearing accuracy in a single sounding action. The only change
required is the generation of two deflected beams and some simple computations. The new
approach to mono-pulse technique, with application of digital signal processing is presented
in the paper. The computer simulations proved, that good bearing accuracy can be obtained
even for a relatively low signal to noise ratio.
