Problems solved by technology

However, the hardware-in-the-loop radar network simulation also requires multiple sets of hardware-in-the-loop simulation equipment. When the number of radars to be simulated is large, the cost and complexity of the simulation system are unacceptable

Abstract

The present invention relates to a time-division multiplexing technology-based networked ground-based radar semi-physical system. The system includes an X-band command and control radar semi-physical verification system, a Cobra Dane radar semi-physical verification system and an early warning radar semi-physical verification system; the three verification systems work jointly so as to simulate required battlefield environments more completely, and therefore, fidelity is high, implementation possibility is higher; and a time-division technology, semi-physical model and functional auxiliary verification module-combined method is adopted, and therefore, the costs of actually-created semi-physical equipment are decreased, a test method is simplified, and test difficulty is reduced.

Description

technical field [0001] The invention relates to a networked ground-based radar semi-physical system based on time-division multiplexing technology, which belongs to the construction technology of semi-physical test systems. Background technique [0002] Radar networking has the advantages of expanding time and space detection range, improving radar measurement accuracy, detection capability and radar observation data rate, and can perform anti-stealth and anti-jamming, so it has been widely used in the military. At present, in the mathematical simulation system, the simulation of the networked radar is relatively easy to realize, but the disadvantage is that the authenticity of the simulation is completely determined by the simulation model. If all physical simulations are used, multiple radars need to be equipped at the same time according to the networking requirements. At this time, the authenticity of the countermeasure simulation can be best guaranteed, but the cost of ...
