Radio Altimeter MY-3001M

The MY-3001 series altimeters include models such as MY-3001A, MY-3001B, MY-3001C, MY-3001D, MY-3001E, MY-3001F, MY-3001G, and MY-3001H; as China’s smallest and lightest full-function radio altimeters that meet aerospace standards, they serve as key components for longitudinal height channel control and can be widely used in cruise missiles and UAVs to measure altitude relative to the sea or ground. The MY-3001 series altimeters adopt linear modulation coefficient technology adaptive to altitude changes and echo signal narrow-band receiving technology to enhance the product’s resistance to active interference, use coherent local oscillator mixing to achieve superior performance in resisting co-frequency asynchronous interference, employ echo signal spectrum front detection technology to improve tracking accuracy, and follow the three design principles of serialization, standardization, and modularization to enable high-speed production; additionally, built on a closed-loop tracking system, they integrate digital control technology, microwave integration technology, and hybrid integration technology to realize ultra-miniaturization of the product. As China’s first full-function radio altimeter, the series is known as the "high-speed rail ticket" in the industry.

The MY-600L altimeter is a fixed-frequency pulse radar altimeter developed for a specific type of aircraft, while the MY-800L altimeter is a frequency-agile pulse radar altimeter designed for another particular aircraft model. Both altimeters find wide application in cruise missiles and aircraft, serving to measure the relative height above the sea or ground. Notably, the MY-600L features a design approach centered on serialization, standardization, and modularization, which endows it with favorable product inheritance, high maturity, and reliable performance.

The MASS-06 Echo Signal Simulation Excitation System, hereinafter referred to as the "Simulation Excitation Source", is a dedicated equipment designed for the hardware-in-the-loop (HIL) simulation of radio altimeters. It serves as a key component in replicating real-world echo signal scenarios, providing targeted excitation signals that enable the radio altimeter to operate under simulated physical conditions—effectively bridging the gap between theoretical testing and actual operational environments to validate the altimeter’s performance, responsiveness, and reliability.

The MY-919 radio altimeter is a new-generation altitude-measuring radar system designed for a specific type of aircraft; as a miniaturized, full-function radio altimeter that complies with avionics standards, it serves as a key component for the control of an aircraft’s longitudinal altitude channel and can be widely applied in large aircraft and unmanned aerial vehicles (UAVs). A radio altimeter based on a frequency-modulated continuous wave (FM CW) closed-loop tracking servo control measurement system, the MY-919 adopts linear modulation coefficients adaptive to altitude changes and narrow-band reception of echo signals, granting the product strong resistance to active interference; it uses coherent mixing reception, which delivers superior performance in resisting co-frequency asynchronous interference and ensures the product has good electromagnetic compatibility; it employs echo signal spectrum front detection technology, enabling the product to maintain high precision in tracking and measurement; it follows serialization, standardization, and modularization design principles, resulting in good product inheritance; and it integrates digital frequency-domain processing and control, microwave integration technology, and hybrid integration technology, making the product stable in performance, mature, and reliable.
