| Abstract: | This paper presents a system simulation method of pulse Doppler radar altimeters with frequency agility.Based on available data and theoretical models,the method of computing the amplitudes of the radar returns and the computer simulation of this neW altimeters is presented. An algorithm of detecting targets is proposed and the probability of detection and the false-alarm probability of this altimeter are calculated according to the system simulation results,which shows this altimeter are calculated according to the system simulation results,which shows this altimeter can be used on all kinds of aeroplane to detect altitudes. |
