MY-5001B Radio Altimeter for Sea Condition Identification

The MY-5001B radio altimeter is an all-solid-state C-band device featuring a frequency-modulated continuous wave (FM-CW) system, a constant differential beat frequency, and a closed-loop tracking and measurement mechanism. It ensures a constant beat frequency through servo control of the slope of the sawtooth wave that modulates the microwave oscillator, thereby achieving automatic height tracking. This altimeter incorporates a suite of advanced technologies, including narrowband reception, weighted frequency discrimination, equivalent spectrum leading edge detection, gain PID control, instantaneous sensitivity compensation, temperature compensation, horizon frequency selection design, and power silence. These technologies collectively endow it with advantages such as accurate height measurement, stable tracking, adaptability to various terrains, a wide height measurement range, high precision, and strong anti-interference capabilities.
