Three Element Beam forming Algorithm with Reduced Interference Effect in Signal Direction
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
The beam forming algorithm simulated in this project is motivated by analyzing a low-cost radar system that provides wide spatial coverage and very rapid target detection as well as tracking.Desigining towards these goals, a reasonable and mostly generic receiver would employ a three-antenna receiver. Because the minimum number of sensing elements needed to determine two dimensional angles is three the system cost has been mostly minimized. In this project 1 consider the problem of using our low cost system to detect and estimate the direction of arrival (DOA) of a desired signal in the presence of a dominant interference signal. Unlike most direction of arrival (DOA) estimation algorithms, the proposed algorithm does not use grid search. Instead the estimates result from a closed-form solution, a great advantage in time-sensitive applications. Additionally, we carry out numerical simulations and results will be analyzed to demonstrate that our algorithm is capable of achieving more reliable DOA estimates than those found with the well-known multiple signal classification algorithm. Finally, a complete radar signal processing example will be presented. MATLAB/GNU OCTAVE simulation tool will be used for simulation. The simulation results, applications, merits and demerits of proposed approach will be analyzed and will be documented.
