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.

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.

The MY-919 radio altimeter is a new-generation altitude-measuring radar system designed for a specific type of aircraft; as a miniaturized, full-function radio altimeter that complies with avionics standards, it serves as a key component for the control of an aircraft’s longitudinal altitude channel and can be widely applied in large aircraft and unmanned aerial vehicles (UAVs). A radio altimeter based on a frequency-modulated continuous wave (FM CW) closed-loop tracking servo control measurement system, the MY-919 adopts linear modulation coefficients adaptive to altitude changes and narrow-band reception of echo signals, granting the product strong resistance to active interference; it uses coherent mixing reception, which delivers superior performance in resisting co-frequency asynchronous interference and ensures the product has good electromagnetic compatibility; it employs echo signal spectrum front detection technology, enabling the product to maintain high precision in tracking and measurement; it follows serialization, standardization, and modularization design principles, resulting in good product inheritance; and it integrates digital frequency-domain processing and control, microwave integration technology, and hybrid integration technology, making the product stable in performance, mature, and reliable.

The MY-2001 altimeter is a new-generation radar altimeter designed for small missile aircraft; as a compact, full-function radio altimeter that meets aerospace standards, it serves as a key component for longitudinal height channel control and can be widely used in cruise missiles and UAVs to measure altitude relative to the sea or ground. The MY-2001 adopts linear modulation coefficient technology adaptive to height changes and echo signal narrow-band receiving technology to enhance the product’s resistance to active interference, uses coherent local oscillator mixing to achieve superior performance in resisting co-frequency asynchronous interference, employs echo signal spectrum front detection technology to improve tracking accuracy, and follows the three design principles of serialization, standardization, and modularization to ensure good product inheritance; moreover, built on a closed-loop tracking system, it integrates digital control technology, microwave integration technology, and hybrid integration technology to realize product miniaturization.
