| Abstract: | According to characteristic of anti-radiation missiles （ARMs） and their velocity and acceleration features in radar echoes, an ARM detection technique based on external non-cooperative illuminators is investigated. Detection range of the radar system is simulated; firstly acceleration of ARM is obtained with ambiguity function and short time Fourier transform algorithm; then carry out ARM＇s echo accumulation through de-chirping. This technique can effectively detect ARMs and give warning. |
