MAST-09 Radio Altimeter Detection Unit

The MY-600L altimeter is a fixed-frequency pulse radar altimeter developed for a specific type of aircraft, while the MY-800L altimeter is a frequency-agile pulse radar altimeter designed for another particular aircraft model. Both altimeters find wide application in cruise missiles and aircraft, serving to measure the relative height above the sea or ground. Notably, the MY-600L features a design approach centered on serialization, standardization, and modularization, which endows it with favorable product inheritance, high maturity, and reliable performance.

The MASS-06 Echo Signal Simulation Excitation System, hereinafter referred to as the "Simulation Excitation Source", is a dedicated equipment designed for the hardware-in-the-loop (HIL) simulation of radio altimeters. It serves as a key component in replicating real-world echo signal scenarios, providing targeted excitation signals that enable the radio altimeter to operate under simulated physical conditions—effectively bridging the gap between theoretical testing and actual operational environments to validate the altimeter’s performance, responsiveness, and reliability.

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 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.
