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.
