Aimed at solving the problem of big error between the measured data and the calculated results of traditional adjacent interference model, the model of signal-to-noise ratio and the model of nonlinear response at receiver radio frequency front end are combined. Considering the noise generated by frequency mixing between adjacent frequency interference signal and the local oscillator phase noise, the model of the reduction of very high frequency (VHF) radio sensitivity is proposed by giving a noise correction factor. The error of the approach is about 3 dB compared with the typical measured data. The comparison between the calculated results and test data shows that the approach can describe the sensitive characteristics of adjacent channel interference accurately. The assessment method of the adjacent channel interference between airborne radios is presented by giving the calculation flow with helicopter fleet application example, which verifies the applicability and effectiveness of the above methods and shows that the approach and assessment method have certain engineering application value.
