The thesis develops the theory of the maximum signal/noise ratio adaptive algorithm (MSN) for use in receiving arrays, from the techniques of main beam and null steering. From considering aerial array null steering systems the simple sidelobe canceller is introduced and discussed. The MSN algorithm is derived and illustrated by considering a simple three element array. In addition two different methods of implementing the algorithm are discussed. The operation of multi-element adaptive arrays is investigated with computer simulation programmes. Simulation results from both matrix inversion and circuit feedback implementations of the algorithm are presented. The MSN adaptive algorithm is also applied to temporal filters, a specific application of which is in radar moving target indicators. A simple three element non-recursive digital adaptive filter is studied with the aid of a simulation programme. The results obtained from the simulation are used to design a temporal digital adaptive array, (TDAA). The design and subsequent performance of the TDAA is discussed. The advantages and disadvantages of the MSN algorithm are presented, and possible applications and improvements are also discussed.
