6U module radio altimeter HY-919

HY-919 radio altimeter is a new generation of height measurement radar system designed for a certain type of aircraft. It is a miniaturized and fully functional radio altimeter in line with avionics standards. It is a key component of aircraft longitudinal height channel control, and can be widely used in large aircraft and UAV. HY-919 is a FM continuous wave closed-loop tracking servo control measurement system radio altimeter, which adopts linear modulation coefficient adaptive height change, narrow-band receiving of echo signal, strong anti active interference ability of the product; adopts coherent mixing receiving, with superior anti same frequency asynchronous interference performance, good electromagnetic compatibility of the product; adopts echo signal spectrum front detection technology, the product can keep up with the market High precision of tracking measurement; adopting seriation, standardization and modularization design, good product inheritance; adopting digital frequency domain processing and control, microwave integration technology and hybrid integration technology, the product performance is stable, mature and reliable.
