Abstract
The detection performance of focused beam-forming when the focusing depth-of-field is mismatched is analyzed. Several cases are simulated for changing processing frequency, target azimuth and distance. By analysis, the FCBF is more sensitive to the mismatch of depth-of-field when dealing with a high-frequency, near and vertical target. In application, multi depth-of-field comparison should be carried out to obtain more accurate DOA estimation results.
