MDG-400 Radio Altimeter

The MDG-400 radio altimeter operates in the C-band and adopts a frequency-modulated continuous wave (FMCW) working system, with its antenna utilizing a transmit-receive separation mode. Prior to missile launch, the altimeter (serving as the height-fixing device) is powered on, and it undergoes self-check and height presetting via the communication interface. After the missile is launched, the radio frequency (RF) module is activated, and frequency variation parameters are set based on the preset height. When the preset height is achieved, the altimeter outputs height-fixing command information and telemetry data. The MDG-400 altimeter features mature technology; its adoption of frequency-modulated continuous wave (FMCW) technology endows it with the advantages of compact size and a large height measurement range.
