Abstract:

The work of the VHF adaptive antenna development task is reported. An adaptive-antenna test bed was assembled, including a programmable real-time signal processing system. Power-ratio inversion PRI and eigenvector-weighting EV adaptive algorithms were investigated analytically and by means of simulation, and implemented in two-element form on the real-time processor. These algorithms tend to separate incoming signals into different output channels according to their relative strengths, and do not require a priori information on the communications being received. Adaptive antennas, VHF communications.
