Construction and Simulation of the Signal Model Based on L Array

In array signal processing,the estimation of the signal parameters is very important.However,there are lots of difficulties in the real time application of the array signal processing,such as large amount of the operations and memories because of the complex structure of the plane array.Based on all these problems,here,some new improvements are described and with a constructed L array,a method based on the rotational invariance techniques(ESPRIT)for calculating the frequency and the two-dimensional arrival angle of the signal source is presented.The frequencies and the angles can be paired automatically,and the structure is much simpler than that of the plane array.The simulation results are perfect,and clearly,the operation amount is relatively smaller,so it will be more practical and feasible.
