A new method for ARM detection based on Adaptive Linear Prediction Error Filter (ALPEF) is proposed in this paper. The method is proved to be fast, reliable for detecting ARM signal in a very low aircraft to ARM signal ratio. Its mechanism is based on the elimination the strong aircraft signal from the radar echoes. Computer simulation results show that a very good detection performance is achieved in a -20 dB aircraft to ARM signal ratio, so that a reliable early warning of ARM launching can be given.
