Understanding and Optimizing Multiple Side-Lobe Canceler Operation.
Abstract
A simple technique was developed for analyzing the operation of multiple side-lobe canceler loops on signals from multiple jammers. This technique is a simple graphical method that requires very little mathematics yet gives its user a feel for canceler operation that is missing in the conventional mathematical approach. Examples of the application of this technique demonstrate the falseness of the common belief that 'N' cancelers can adequately cancel the signals from 'N' jammers when the jammer geometry is variable and the canceler antenna geometry is fixed. The use of this technique is recommended for determining the number and locations of auxiliary antennas required to protect a given radar from a given number of jammers in arbitrary locations.
