(b) the target motion parameters can be easily estimated by FFT without any searching process; (c) the phase difference eliminates the Doppler ambiguity, thus the high speed of target can be accurately estimated; (d) it achieves a good balance between the computational cost and detection ...
This computation integrates the displacements at microphone position with a time delay and an attenuation determined by the virtual microphone position above the drumhead. Thereby, the attenuation d/r(x,y), with r(x,y) being the distances between the respective points on the membrane and the ...
