Beside, it has studied the antijamming technology in time domain with emphasis.In the study of interference detection technology, this article systematically describes and stimulates energy detection and Spectral Correlation Function (SCF) based plan. This paper proposes an improved program based on autocorrelation function, whose main superiority is that in time domain, the computation load is smaller than SCF and the detection is more accurate.This article selectively analyzes and improves a DAA plan which is based on power auto-adapted pattern. The DAA plan makes improvement in order to avoid interference with the primary consideration and establish the special flow to avoid mistakenly detecting. The improved DAA plan realizes the optimal interference avoiding effect at the price of transmission efficiency. This article has finally simulated two kinds of DAA plans.
