Abstract :
Some radio equipments work in high-frequency of 3 MHz-30 MHz to detect target. In this band, the real data has indicated that there is obvious meteor trail interference. The interference has adverse effect on the range and Doppler information detection of the target which may lead to these equipments not working normally. Based on the scatter feature of meteor trail, combined with such signal processing technique as ADBF, the meteor trail interference model is built. This model can help to research the technique for suppressing the meteor trail interference. Compared simulation results with real data, it verified that the model is validity
