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.

MY-70D Anti Jamming Radio Altimeter

Operating in the C-band, the MY-70D radio altimeter employs a frequency-modulated continuous wave (FMCW) operating system and incorporates closed-loop tracking measurement technology, equipping it with the capability to resist same-frequency asynchronous interference. This ensures that when multiple aircraft take off and fly simultaneously, their altimeters do not interfere with one another. To achieve resistance against active interference, the altimeter adopts a range of measures, including anti-blocking, anti-burnout, power control, beam control, frequency agility, and frequency modulation (FM) technology. Furthermore, it features silent power supply control for its microwave components; its antenna is fitted with a band-pass filter, and a customized radome with frequency-selective functionality is utilized—these design elements enable the altimeter to achieve a wave transmission rate of ≥85% for the operating frequency within the band and less than 10% for out-of-band frequencies, thereby realizing stealth capabilities.
