2 results about "Rapid convergence" patented technology

The invention discloses a wide signal measuring method and device considering the signal-to-noise ratio, and belongs to the technical field of electronic reconnaissance and radar signal processing, and the method comprises the steps: receiving a wide input signal, carrying out the detection and amplitude comparison processing of the signal, when the signal amplitude is greater than a preset threshold value, controlling the gating of a branch 1, and directly outputting the signal, when the signal amplitude is smaller than the threshold value, controlling the gating of the two branches, and outputting the signal after being amplified; and controlling the input signal to be stabilized to a receiving standard power value through making the processed signal pass a numerical control damper. According to the method, the received wide signals are distinguished, it is guaranteed that the signal-to-noise ratio of the input signals is not deteriorated through different links, the error detection rate is reduced, meanwhile, rapid convergence and stable output of the amplitude are achieved, and the method is simple in link and gives consideration to economic benefits.
