A method of reducing concentrated interference at the receiver output signal with a chirp

摘要

Method attenuation concentrated interference at the receiver output with the chirp signal comprising weakening element signal if it contains a concentrated interference, characterized in that the detection concentrated interference occurs after discharge from the signal output from the receiver chirped Ionosonde A (t) by filtration using noise signal bandpass filters A (t), wherein the noise component and the signal A (t) and the signal at the receiver output A (t) of duration t cells are divided into K duration Ttak to comparable wasp Δfbyla frequency equal to the characteristic values ​​of the spectral width centered interference, and interference from the selection concentrated signal A (t) and its attenuation in the signal A (t) produced through the use of coarse error detection criteria in the experimental measurements: if the standard deviation σotschetov k- a member of the signal (t) with band Δfvypolnyaetsya otsenkas - standard deviation σ samples; E - σ kurtosis samples, the k-th element of the signal a (t) is not attenuated, if this inequality for certain k-element is in the Follow the important, this signal element A (t) is attenuated by zero samples.
