how to program a delay sum beamformer for a specific target direction

i want to design a delay sum beamformer for an 8 element linear sensor array for sonar, for a target direction of 60 degrees and sensor spacing of 1meter. If I have 8 delayed signals, how can i generate delay sum beamformed signal.

You can use phased.TimeDelayBeamformer to do this if you have access to Phased Array System Toolbox.
