Simulation Study of Jammer Nulling Trade-Offs in a Reactively Steered Adaptive Array

摘要

Antenna arrays that operate at frequencies up to 6 GHz or so on air-launched guided missiles are necessarily compact because of limited space. Research has been in progress since FY82 on a compact adaptive array that uses reactively loaded parasitic elements for pattern control. This report describes a study of this class of array whose purpose is to examine the trade-offs available among number of elements, element spacing, and number of nullable jammers. The research is part of a continuing effort to explore novel radio frequency radiating and receiving structures for application to airborne communications and radar system.
