Could everyone help me how to plot an make a plot result like this photo (attached) <http://i45.tinypic.com/2agkuo9.png> I'm doing my final project, I want to detect a noise source underwater (the noise will be the the noise of ship maschine) in near field (spherical wave-front) using beamforming, I'll use 5 hydrophone array (cross shape). I'm not using time-delay beamforming so the things that will be measured are the power of signal source and the power pressure that arrived to each microphone to get the exact location of the noise source. My reference are "*__Detection of Noise Sources in a Cavitation Tunnel by using Beamforming Method by Jeong Hak Lee, Jong Soo Seo and Soo Cheol Shin__*" "J. W. Choi and Y. H. Kim, “Spherical Beamforming and MUSIC Method for Estimation of Location and Strength of Spherical Sound Sources”, Mechanical Systems and Signal Processing, 9(5), 569-588 (1995)**" and "*Y. C. Choi and Y. H. Kim, “Noise Source Identification in a Reverberant Field Using Spherical Beamforming”, Inter-noise 2001*"
