MASS-03 Radio Altimeter Continuous Echo Signal Simulator
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.
Electronic Countermeasure Radio Altimeter MY-18A、19A
Developed to meet the requirements of electronic countermeasures and terminal penetration, the MY-18A and MY-19A electronic countermeasure radio altimeters incorporate a range of advanced technologies including frequency agility, radiated power control, beam control, anti-burnout, anti-blocking, and echo frequency-domain processing—endowing them with excellent anti-jamming performance. Meanwhile, these altimeters also integrate a sea state identification function, which leverages information such as echo spectrum broadening, Doppler frequency, and altitude under different sea conditions to achieve accurate sea state recognition.
MY-70D Anti Jamming Radio Altimeter
Operating in the C-band, the MY-70D radio altimeter employs a frequency-modulated continuous wave (FMCW) operating system and incorporates closed-loop tracking measurement technology, equipping it with the capability to resist same-frequency asynchronous interference. This ensures that when multiple aircraft take off and fly simultaneously, their altimeters do not interfere with one another. To achieve resistance against active interference, the altimeter adopts a range of measures, including anti-blocking, anti-burnout, power control, beam control, frequency agility, and frequency modulation (FM) technology. Furthermore, it features silent power supply control for its microwave components; its antenna is fitted with a band-pass filter, and a customized radome with frequency-selective functionality is utilized—these design elements enable the altimeter to achieve a wave transmission rate of ≥85% for the operating frequency within the band and less than 10% for out-of-band frequencies, thereby realizing stealth capabilities.

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.

The MY-5001B radio altimeter is an all-solid-state C-band device featuring a frequency-modulated continuous wave (FM-CW) system, a constant differential beat frequency, and a closed-loop tracking and measurement mechanism. It ensures a constant beat frequency through servo control of the slope of the sawtooth wave that modulates the microwave oscillator, thereby achieving automatic height tracking. This altimeter incorporates a suite of advanced technologies, including narrowband reception, weighted frequency discrimination, equivalent spectrum leading edge detection, gain PID control, instantaneous sensitivity compensation, temperature compensation, horizon frequency selection design, and power silence.

MDG-100 Radio Height Setting Device
The MDG-100 radio altimeter operates in the C-band and adopts a pulse Doppler working system. Its sensitive device is of the heterodyne type, and the circulator at the antenna terminal uses a transceiver common-mode design. With mature technology, this altimeter is installed on missiles and serves as a control component for altitude fuzes. It features capabilities such as high burst altitude, strong adaptability to high falling speeds, and excellent performance in resisting ground clutter and sea clutter. Additionally, it employs pseudo-random pulse modulation technology: the pulse period varies randomly within a specified range, making it difficult for jammers to identify the initial modulation pulse of the fuze signal and further predict the delayed pulse. This design effectively enhances the altimeter’s resistance to active interference.
