Subminiature Radio Altimeter MY-70B

The MY-70B radio altimeter is a solid-state C-band radio altimeter system based on frequency-modulated continuous wave (FMCW) technology, characterized by constant beat frequency and closed-loop tracking measurement. It maintains a constant beat frequency by servo-controlling the slope of the sawtooth wave that modulates the microwave oscillator, thereby achieving automatic altitude tracking. Under the condition of constant beat frequency, the measured altitude is proportional to the modulation period; thus, altitude information can be obtained by measuring the modulation period, and the system then converts this information into an altitude voltage for output. The MY-70B altimeter possesses excellent anti-jamming performance, owing to its adoption of a narrow-band receiver (with gain adjustable according to altitude) as well as technologies including equivalent spectrum front-end detection, weighted frequency identification, and automatic servo tracking. In terms of component design, its high-frequency components implement microwave integration while its low-frequency components adopt a modular design—these measures collectively enhance the product’s reliability, anti-interference capability, and electromagnetic compatibility. Additionally, the MY-70B altimeter uses RS422 and CAN protocols for its interface output, which further improves the reliability of the product’s data transmission.
