Description

Technical Field

[0001] This invention belongs to the field of target simulation and is a radar target training optimization method and system based on scenario simulation. Background Technology

[0002] Radar target drills refer to the process of systematically testing and verifying the radar system's detection, tracking, and identification functions, as well as the operators' tactical response capabilities, by simulating various targets and complex environments that radar may encounter in actual operation.

[0003] The modern electromagnetic environment is becoming increasingly complex, and radars face multi-dimensional electronic threats. Traditional radar target training methods are no longer sufficient to meet operational needs. Early training relied on field tests with live equipment, which were limited by geography and weather, and could not reproduce complex interference scenarios, resulting in high testing costs and long deployment cycles.

[0004] While digital simulation technology is gradually replacing traditional methods, it still has significant shortcomings. Existing systems mostly simulate single types of interference, making it difficult to reproduce complex scenarios involving "dynamic interference + multi-target echoes," resulting in low efficiency in verifying anti-jamming algorithms. Training scenarios often pre-set fixed target trajectories, failing to simulate enemy tactical maneuvers and exposing the limitations of static training. Furthermore, the effectiveness evaluation system is incomplete, focusing primarily on functional verification and lacking quantitative evaluation of radar operation methods. It also relies on manual debriefing, which is highly subjective and time-consuming.

[0005] Radar operators should possess full-process response capabilities, but existing systems cannot provide closed-loop feedback. These deficiencies have spurred the development of radar target training optimization systems and methods based on scenario simulation to improve the realism, flexibility, and scientific rigor of training effectiveness assessments.

[0006] The existing invention patent application document CN119224708A, entitled "Radar Target Echo Signal Generation Method," includes the following steps: loading and parsing an XML file describing a radar echo simulation scenario to obtain parsing results including the simulation scenario duration, parameters of several targets, and radar parameters; dividing the simulation scenario duration into several simulation slices based on the radar pulse repetition period (PRI); performing a first simulation calculation operation on each simulation slice using a multi-core parallel thread of a GPU based on the parsing results; traversing several simulation slices with each PRI as the simulation step size; performing a second simulation calculation operation based on the first simulation calculation operation results of each PRI using a multi-core parallel thread of a GPU to obtain echo signals of several targets; and superimposing the echo signals of several targets to obtain the radar target echo signal. However, the above-mentioned published invention mainly focuses on virtual target generation and does not consider integrated planning of physical targets or the generation and planning of targets combining virtual and real elements.

[0007] In summary, existing technologies suffer from technical problems such as insufficient number of physical targets, difficulty in scheduling physical targets, and difficulty in realistically simulating opposing targets when conducting simulations of complex environments. Summary of the Invention

[0008] The technical problem to be solved by the present invention is: how to solve the technical problems faced by existing technologies in simulating complex environment exercises, such as insufficient number of entity targets, difficulty in scheduling entity targets, or difficulty in realistically simulating the opponent's target.

[0009] This invention solves the above-mentioned technical problems by employing the following technical solution: A radar target training optimization method based on scenario simulation includes: S1.

[0014] In a more specific technical solution, S2 utilizes the entity target support subsystem to perform functions such as route planning and formation management for entity targets according to the target support plan, and provides real-time guidance and control for entity targets, as well as data sharing and interconnection.

[0015] In a more specific technical solution, S2 uses target planning operations to allocate target groups, task areas, task types, and task sequences, completing both pre-assignment and real-time task assignment; it also uses target planning operations to receive and parse flight missions issued by the mission planning and guidance system, and upload the real-time status of the targets. Target monitoring operations receive and transmit target status data.

[0016] In more specific technical solutions, target planning operations are used to plan cruise, mission, and recovery routes for multiple targets, with no fewer than two pre-programmed routes or fully autonomous flight routes.

[0017] In a more specific technical solution, target monitoring is used to display the target's flight attitude angle, altitude, speed, flight path, and latitude and longitude coordinates in real time using two-dimensional animation and digital methods. When a remote control command is issued, the command currently sent from the ground and the current command status of the target are displayed. Based on the target monitoring results, a warning signal is generated and output.

[0018] This invention provides a combined virtual and real target support environment and a complex electromagnetic environment. It enables the overall planning and target management of aerial targets during integrated exercises, and meets the requirements for generating multiple batches of target signals for radar control exercises.
