MDG-300 Radio Altimeter

MDG-200 Radio Altimeter

The MDG-200 radio height-setting device operates in the C-band and adopts a monopulse working system. Its sensitive component is of the heterodyne type, and the circulator at the antenna terminal uses a transceiver common-mode configuration. Prior to missile launch, the height-setting device needs to be powered on; it then performs a self-check and completes height setting via the communication interface. After the missile is launched, the radio frequency (RF) module is activated, and a gate is set based on the preconfigured height. When the preset height is reached, the device outputs height-setting command information and telemetry data. The MDG-200 height-setting device features mature technology: the monopulse design enhances the altimeter’s height measurement performance, and the device also has the characteristic of not being affected by the carrier’s speed.

Radio Altimeter MY-3001D

The MY-3001D radio altimeter incorporates two key technologies: a linear modulation coefficient technology that adapts to altitude changes and a narrow-band receiving technology for echo signals, both of which effectively enhance the product’s resistance to active interference. It also adopts coherent local oscillator mixing, granting it superior performance in resisting co-frequency asynchronous interference, and employs echo signal spectrum front-edge detection technology to boost tracking accuracy. In terms of design, the altimeter follows the principles of serialization, standardization, and modularization. While retaining its closed-loop tracking system, it further integrates digital control technology, microwave integration technology, and hybrid integration technology to achieve product modularization. Additionally, it is equipped with a silent function, which further improves the product’s anti-interference capability. This radio altimeter is applicable to cruise missiles and unmanned aerial vehicles (UAVs) for measuring the altitude relative to the sea surface or the ground.

Subminiature Radio Altimeter MY-70B

The MY-70B radio altimeter is a solid-state C-band radio altimeter system based on frequency-modulated continuous wave (FMCW) technology, characterized by constant beat frequency and closed-loop tracking measurement. It maintains a constant beat frequency by servo-controlling the slope of the sawtooth wave that modulates the microwave oscillator, thereby achieving automatic altitude tracking. Under the condition of constant beat frequency, the measured altitude is proportional to the modulation period; thus, altitude information can be obtained by measuring the modulation period, and the system then converts this information into an altitude voltage for output. The MY-70B altimeter possesses excellent anti-jamming performance, owing to its adoption of a narrow-band receiver (with gain adjustable according to altitude) as well as technologies including equivalent spectrum front-end detection, weighted frequency identification, and automatic servo tracking. In terms of component design, its high-frequency components implement microwave integration while its low-frequency components adopt a modular design—these measures collectively enhance the product’s reliability, anti-interference capability, and electromagnetic compatibility. Additionally, the MY-70B altimeter uses RS422 and CAN protocols for its interface output, which further improves the reliability of the product’s data transmission.

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.

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.
