Abstract
An experimental three-beam adaptive array at 43 Ghz, initiated under a previous Contract, is near completion. The array is configured as a vehicle to investigate the performance of different interference nulling algorithms experimentally. It has two IF channels to separate in-band dehopped signals from out-of-band interferences in a frequency hoped system. A real-time-processor based on a digital signal processing chip, the AT&T DSP32 is used to perform beam control algorithms. A software package AJSIM based on a Graphical User Interface (GUI) is being developed for the control, data collection and display of the experiments. The package also supports simulation of larger arrays under different user-jammer scenarios using different algorithms. A secondary objective is the investigation of a new angle detector for spatial tracking in heterodyne laser space communications. TRUNCATED
