Title: FUTURISTIC ADAPTIVE SYSTEMS
Abstract: In the adaptive beamforming methodology used in the signal processing community, typically the adaptive weights are connected to each one of the antenna elements in the array and the processing information is generated over time, as the correlation matrix of the data needs to be formed. In the electromagnetic community however, the procedure is to carry out beam forming. However, in a system implementation, the practical requirements are quite different from these two disjoint theoretical philosophies, as in a real system the objective is to extract the signal of interest out of interferers, clutter, jammers and on. What makes the problem interesting and the classical solution methodologies not relevant in practice, as illustrated by the non-existence of a real system after fifty years of the discovery the adaptive methodologies, is because it is not only necessary to cancel the interferers and extract the signal of interest when they are located by less than a beam width of the array, but also, the direction of the arrival of the interferers are not known a priori as it is a part of the solution process itself and therefore beam forming has little use! In addition there can be blinking jammers which make a temporal implementation of the adaptive methodology not meaningful.

It is important to note that an antenna is a temporal filter as one can perform temporal filtering as is usually done in the signal processing community but it is also a spatial filter which is the methodology pursued in the antenna community. However, these two diverse properties are interrelated and that is why one solves Maxwell equations as these two properties are related exactly through the Maxwell equations. Understanding of this basic principle of antenna engineering can make it possible to address problems which are difficult to solve using exclusively only any one of these classical methodologies.

The objective of this short course is to illustrate that a same antenna array can be used to detect signals coming from two different directions at two different frequencies using the same antenna array. This process can be carried out in the presence of both coherent and incoherent interferers also arriving at different frequencies from different directions and impinging on the same antenna array. This methodology can not only address the case of using directive antennas as elements but it can operate in the presence of other electromagnetic artifacts which can distort their functional properties and in the presence of blinking jammers.
