MAST-12 Radio Altimeter Exciter

The MY-3001m radio altimeter is a radar altimeter developed for the Rainbow XX UAV by a specific institute. It is widely used in UAVs to measure the altitude relative to the sea surface or the ground. This altimeter incorporates a linear modulation coefficient technology adaptable to altitude changes and a narrow-band receiving technology for echo signals, which enhances the product’s resistance to active interference. It also adopts coherent local oscillator mixing, delivering superior performance in resisting synchronous interference, and employs echo signal spectrum front-edge detection technology to improve tracking accuracy. Additionally, it features a three-dimensional design based on serialization, standardization, and modularization, endowing the product with excellent inheritance, maturity, and reliability. While retaining the closed-loop tracking system, the MY-3001m radio altimeter further adopts digital control technology, microwave integration technology, and hybrid integration technology to achieve product modularization. Moreover, its receiver is equipped with dual filters, which further boosts the product’s anti-interference capability.

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.

The MASS-03 Radio Altimeter Continuous Echo Signal Simulator is a specialized testing device designed to generate stable, continuous echo signals that replicate real-world altitude-related signal environments for radio altimeters. Tailored to support the development, calibration, and performance verification of radio altimeters, it accurately simulates various echo signal characteristics (such as amplitude, frequency, and delay) corresponding to different altitude scenarios, enabling users to test critical functions of radio altimeters—including height measurement accuracy, tracking stability, and anti-interference performance—under controlled laboratory conditions. By providing reliable, repeatable continuous echo signals, the simulator eliminates the need for costly and complex field tests, streamlining the testing process while ensuring radio altimeters meet design specifications for accuracy, stability, and robustness in practical operation.

The MAST-09 Radio Altimeter Detection Unit is a compact, aerospace-grade component that monitors, validates, and processes radio altimeter data for aircraft. It filters interference, cross-references data with other flight sensors, and detects faults (e.g., signal loss, calibration drift) to deliver reliable terrain-relative altitude info—critical for safe takeoff, low-altitude flight, approach, and landing, even in low visibility. Built to meet strict aerospace standards (e.g., DO-160, DO-178), it withstands extreme environmental conditions, suiting commercial and military aircraft.
