Small radio altimeter HY-28A、HY-24(XXX-28A、XXX-24)

HY-28A、HY-24（XXX-28A、XXX-24） are miniaturized C-band full-function radio altimeters that meet the aerospace standards. They are the key components for longitudinal height channel control, and are specially designed for a certain type of UAV target. It has good anti-interference performance and electromagnetic compatibility ability to measure the height relative to the sea or the ground.
HY-28A、HY-24（XXX-28A、XXX-24）adopt seriation, standardization, modularization and other three design, product inheritance is good, mature and reliable, the product has been widely used in several types of aircraft.
At present, the number of the two types of radio altimeters has exceeded 800 sets.
