Pulse Radar Altimeter MY-600L、MY-800L

The MAST-09 Radio Altimeter Detection Unit is a compact, aerospace-grade component that monitors, validates, and processes radio altimeter data for aircraft. It filters interference, cross-references data with other flight sensors, and detects faults (e.g., signal loss, calibration drift) to deliver reliable terrain-relative altitude info—critical for safe takeoff, low-altitude flight, approach, and landing, even in low visibility. Built to meet strict aerospace standards (e.g., DO-160, DO-178), it withstands extreme environmental conditions, suiting commercial and military aircraft.

The MASS-10 Universal Echo Precision Delay Module, featuring a miniature design and universal continuous simulation capability, is a high-performance component tailored for precise echo signal delay control in radio frequency (RF) testing scenarios. It excels in providing accurate, adjustable delay for echo signals across a wide range of frequencies, making it applicable to various devices like radio altimeters, radars, and other RF-based systems that require reliable echo signal simulation. With its compact size, the module is easy to integrate into limited-space test setups, while the universal continuous simulation function ensures it can replicate diverse real-world signal delay conditions consistently. This module plays a crucial role in verifying the performance of target devices—such as testing their ability to accurately capture and process delayed echo signals—thereby supporting the development, calibration, and quality assurance of RF equipment with high precision and flexibility.

The MDG-300 radio height-fixing device operates in the C-band and adopts a pulse compression system. Its sensitive component is of the heterodyne type, and the circulator at the antenna terminal uses a transceiver common-mode design. Prior to missile launch, the height-fixing device is powered on, and it undergoes self-check and height presetting via the communication interface. After the missile is launched, the radio frequency (RF) module is activated, and a gate is set in accordance with the preset height. When the preset height is reached, the device outputs height-fixing command information and telemetry data. The MDG-300 height-fixing device features mature technology: its pulse compression technology can enhance the altimeter’s height measurement performance, and it has the characteristic of a wide height measurement range. Additionally, the digital pulse compression function based on FPGA (Field-Programmable Gate Array) endows it with advantages such as small size, low power consumption, and low cost.

The MASS-03 Radio Altimeter Continuous Echo Signal Simulator is a specialized testing device designed to generate stable, continuous echo signals that replicate real-world altitude-related signal environments for radio altimeters. Tailored to support the development, calibration, and performance verification of radio altimeters, it accurately simulates various echo signal characteristics (such as amplitude, frequency, and delay) corresponding to different altitude scenarios, enabling users to test critical functions of radio altimeters—including height measurement accuracy, tracking stability, and anti-interference performance—under controlled laboratory conditions. By providing reliable, repeatable continuous echo signals, the simulator eliminates the need for costly and complex field tests, streamlining the testing process while ensuring radio altimeters meet design specifications for accuracy, stability, and robustness in practical operation.
