HY-3001 series altimeters include HY-3001A,HY-3001B,HY-3001C,HY-3001D,HY-3001E,HY-3001F,HY-3001G,HY-3001H and other models. It is the smallest and lightest full-function radio altimeter in China and meets the aerospace standards. It is the key component for longitudinal height channel control. It can be widely used in cruise missiles and UAVs to measure the height relative to the sea or ground.
HY-3001 series altimeter adopts linear modulation coefficient to adapt to altitude change technology and echo signal narrow-band receiving technology to improve the product's anti active interference ability; adopts coherent local oscillator mixing to have superior anti same frequency asynchronous interference performance; adopts echo signal spectrum front detection technology to improve the tracking accuracy; adopts seriation, standardization, modularization and other three kinds of design to realize high-speed production Based on the closed-loop tracking system, digital control technology, microwave integration technology and hybrid integration technology are adopted to realize the ultra miniaturization of the product. It is the first full-function radio altimeter in China and is known as "high-speed rail ticket" by the industry.
