Description

Technical Field

[0001] The invention relates to the technical field of radio detection anti-interference, and in particular to a semi-physical simulation detection system and method for simulating separation of target and interference. Background Art

[0002] When using radio detection equipment to detect targets, it is necessary to consider the detection equipment's ability to resist interference types such as centroid interference and dilution interference in the background environment. Traditional semi-physical simulations are fixed interference types, and rarely mention the evolution of the motion characteristics of interference and targets over time.

[0003] The traditional semi-physical simulation method is to conduct outdoor target detection tests after indoor digital simulation based on target characteristics. Since the indoor digital simulation environment is ideal and the interference characteristics are simple, outdoor target detection usually consumes huge manpower, material and financial resources in test organization, scene layout, location and timing selection, and the cost is high, but the test data obtained is relatively limited. Therefore, the applicability of traditional semi-physical simulation is poor.

[0004] A Chinese patent document with publication number CN118819004A and publication date October 22, 2024 discloses a signal-level radar semi-physical simulation method and system, which belongs to digital simulation. The semi-physical simulation method includes: constructing a signal-level radar digital simulation model; setting input and output protocols to build a universal interface for the system; loading the radar digital simulation model into a real-time simulation machine and setting a semi-physical simulation integration framework for controlling and managing the simulation operation to form a semi-physical simulation system; verifying the semi-physical simulation system to confirm the validity of the universal interface.

[0005] The signal-level radar semi-physical simulation method and system disclosed in the patent document participates in the semi-physical system simulation through the radar digital simulation model, provides a space target detection solution close to the real physical simulation result for the semi-physical experiment, and solves the complex problem of radar physical equipment to a large extent. However, there is still a problem that the digital simulation interference is too idealized, and it cannot simulate the change of the movement speed of the interference over time well, which affects the detection accuracy. Summary of the invention
