Altimeter Transceiver Assembly

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.

Developed to meet the requirements of electronic countermeasures and terminal penetration, the MY-18A and MY-19A electronic countermeasure radio altimeters incorporate a range of advanced technologies including frequency agility, radiated power control, beam control, anti-burnout, anti-blocking, and echo frequency-domain processing—endowing them with excellent anti-jamming performance. Meanwhile, these altimeters also integrate a sea state identification function, which leverages information such as echo spectrum broadening, Doppler frequency, and altitude under different sea conditions to achieve accurate sea state recognition.

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 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.
