Processing of high resolution experimental data of air acoustic sonar system

Test measurements of air acoustic sonar signals are analyzed with CBF, MUSIC and WSF and results are listed. Comparison shows that WSF and MUSIC are better than CBF and, for the tests, WSF is a little better than MUSIC. The above mentioned test data sampled from an air acoustic sonar was processed with a subsystem in the sonar, which incorporated a Transputer 800 chip. This subsystem included an echelon air arry which shows the layout of the measurement system.
