Abstract:

Lossless beam forming networks using phase shifters and quadrature couplers are described. A technique for using the Butler network with randomly spaced arrays is discussed. A synthesis procedure for networks with N-element arrays is described. A method of using these networks with planar arrays is discussed. A least mean square algorithm for the determination of a beam forming network for an arbitrary array and arbitrary beam directions is developed. Computed pattern data for two thinned random planar arrays is included. Author
