A Practical Method For Measuring The Spatial Frequency Response Of Abstract: this communication proposes a new relaxation variable based cost function for the problem of frequency invariant (fi) beampattern synthesis. two constraints in the spatial and frequency domains are imposed on the optimization problem. Additionally, we proposed two fi beamformer design algorithms for focused and shaped beampattern synthesis with accurate spatial frequency response control. numerical results validated the high flexibility and low computational complexity of the proposed algorithms.
Image Science Associates Spatial Frequency Response Target Se1 What is a beampattern and how do we use it?. Based on this principle, we present an iterative fi beampattern synthesis algorithm under arbitrary array configurations. simulation results show the effectiveness of the proposed algorithm in comparison with several popular fi beampattern synthesis techniques. The weighted least squares (wls) based beamformer design can achieve flexible beampattern control via adjusting the wls weighting function inspired by the adaptive array theory (aat). This paper addresses time domain frequency invariant beampattern synthesis under multiple constraints. mainlobe spatial response variation is introduced to characterize the frequency invariance.
