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.

MYQ-02A High Precision Atmospheric Processor

The air data processor is designed to detect the total static pressure or distributed pressure of the airflow approaching an aircraft, thereby enabling the measurement of key flight parameters including Mach number, barometric altitude, vertical velocity, and indicated airspeed. The barometric pressure signals, which are collected from outside the aircraft and serve as the input for the air data processor, undergo processing via a solving circuit. Based on specific algorithms—tailored to factors such as the number of pressure channels, the carrier’s shape, and the distribution of pressure-measuring points—the processor outputs atmospheric parameters (e.g., static pressure, total pressure, barometric altitude, indicated airspeed, and flight Mach number) and transmits these parameters to the flight control unit in digital form.
