RELATION BETWEEN A GENERALIZED WIDEBAND SIGNAL AND ITS EQUIVALENT SHORT PULSE WHEN APPLIED TO ARRAY ANTENNAS

Abstract

The response of an array antenna to a short pulse of bandwidth B can easily be calculated and intuitively explained. However, when pulse compression having a bandwidth equal to this short CW pulse is used to obtain a longer pulse (higher average power) while retaining good range resolution, questions of system response and attainable resolution arise. By treating this problem in general terms, the following theorem covering array responses to a generalized wideband signal (pulse compression, etc.) is proven. Given a generalized signal s(t), with bandwidth B, the response of a time invariant (during signal duration) array antenna to this signal as a function of look angle after element summation and resultant signal match filtering (filter response s*(t) ) will be identical to the response as a function of 0 obtained from a short precise pulse g(t) whose shape is identical to the compressed pulse shape.
