Synthesis of unequally spaced arrays by simulated annealing
Simulated annealing is applied to the synthesis of arrays in order to reduce the peaks of side lobes by acting on the elements' positions and weight coefficients. In the case considered, the number of array elements and the spatial aperture of an unequally spaced array are a priori fixed. Thanks to the high flexibility of simulated annealing, the results obtained for a 25-element array over an ...
متن کاملSpace-Time Adaptive Processing Based on Unequally spaced Antenna Arrays
It is known that the spatial correlation between the desired signal and the undesired signals is an important parameter in adaptive array processing. In this paper, we consider the adaptive antenna of mobile communications under space-time adaptive processing (STAP), where user signals are of multipath rays with different delays, and the space-time correlation functions are employed instead of ...
متن کاملWavelet Shrinkage for Unequally Spaced Data Wavelet Shrinkage for Unequally Spaced Data
Wavelet shrinkage (WaveShrink) is a relatively new technique for nonparametric function estimation that has been shown to have asymptotic near-optimality properties over a wide class of functions. As originally formulated by Donoho and Johnstone, WaveShrink assumes equally spaced data. Because so many statistical applications (e.g., scatterplot smoothing) naturally involve unequally spaced data...
متن کاملMOEA/D with Adaptive IWO for Synthesizing Phase-Only Reconfigurable Linear Arrays
In order to well solve the phase-only reconfigurable arrays synthesis problems, we introduce an adaptive strategy in invasive weed optimization (IWO), and integrate the adaptive IWO (AIWO) into the framework of MOEA/D, a popular multi-objective algorithm. Then, a new version of MOEA/D with adaptive IWO, named MOEA/D-AIWO is proposed in this paper for solving the synthesis problems. In MOEA/D-AI...
