Multinational corporations use ships to transport goods, and tourists use ships to continue their international travels. Therefore, the safe navigation of ships is very important. Due to the many unstable factors on the sea, in order to prevent ships from being damaged remotely, people generally install shipboard defense systems on ships. These systems identify flying objects and intercept dangers. In order to ensure successful defense, a tracking signal compensation system is usually installed. This system uses a Kalman filter to improve the tracking accuracy of targets, thus making the defense more secure.
[0003] However, in practical applications, the complex marine environment and adverse weather conditions can affect the visibility, stability, and accuracy of sensors. Furthermore, atmospheric refraction and scattering can influence electromagnetic wave propagation, thus impacting sensor performance. Atmospheric turbulence can cause signal distortion and fluctuations, affecting sensor resolution and accuracy. Consequently, ship tracking signals may be inaccurate, leading to delayed defense or failure to react in time to potential danger. Therefore, this paper proposes a tracking signal compensation method for shipborne defense to address these issues. Summary of the Invention

[0056] S6. Continuous verification and testing: Conduct continuous verification and testing of the system to confirm the authenticity of the flying object information;
[0057] S7. The command is transmitted to the defense system, and the calculated signal compensation parameters are transmitted to the defense system to adjust the parameters of the defense system to ensure that the target can be accurately tracked and intercepted.
[0058] S8. Field verification and optimization: Collect actual defense data and optimize the sensor fusion algorithm based on the results to ensure that the defense system can still be used effectively under constantly changing conditions.
[0059] Specifically, when intercepting a target flying object, the system first performs basic position and shape identification to determine the interception direction and identifies potential intercepted objects and corresponding interception plans. Then, based on confirmation of the flying object's identity information, an appropriate interception plan is selected. The system then senses the environment around the ship and the flying object to avoid interception errors and applies electronic interference to deviate its flight trajectory, counteracting the interference to prevent errors in detection information. The system also predicts the flying object's trajectory, enabling early interception. By continuously verifying the flying object's identity information, its accuracy is ensured. When the flying object moves into the interception range, its data is transmitted to the defense system, allowing for interception. After interception, the system analyzes and learns from the process, enabling faster interception in similar situations in the future.
[0060] Step S1 includes radar detection and visual detection;
[0061] Radar detection, which uses radar to confirm the location of a flying object;
[0062] Visual inspection uses an image recognition module to confirm the approximate shape of the flying object.
[0063] Specifically, radar can detect distant targets and track their movement, thereby providing crucial early warning and target information. The image recognition module, using cameras, infrared cameras, etc., can provide rich image information for target detection, tracking, recognition, and scene understanding. This enables the system to identify the position and shape of target flying objects, allowing the defense system to develop defense plans against several possible flying objects.
[0064] Step S3 includes adaptive signal processing technology, environmental perception algorithm, and temperature stabilization technology.

[0066] Environmental perception algorithms adjust the sensor's operating parameters according to environmental changes to adapt to different working conditions;
[0067] Temperature stabilization technology ensures that the sensor can maintain system performance under different temperature conditions.
[0068] Specifically, adaptive signal processing technology uses adaptive filtering algorithms to adjust and optimize sensor data in real time in dynamic environments to detect and counteract signal distortion caused by weather, electromagnetic interference, or other environmental factors. It can respond more flexibly to environmental changes and sensor errors. Environmental perception algorithms can monitor and analyze atmospheric conditions, ocean conditions, and electromagnetic environment in real time, and adjust the sensor's operating parameters according to environmental changes to adapt to different operating conditions. Temperature stabilization technology can address the impact of temperature changes on the performance of electronic components, enabling the sensor's cooling or heating system to maintain system performance under different temperature conditions, thereby increasing detection accuracy and ensuring that the interception success rate of the defense system is not affected.
[0069] Step S4 includes electronic jamming and infrared and optical countermeasures;
[0070] Electronic jamming can transmit electronic countermeasures signals to interfere with the radar and communication systems of aircraft.
[0071] Infrared and optical countermeasures are used, employing strong light and lasers while releasing a large amount of heat to disorient the target flying object.
[0072] Specifically, by using strong light and lasers and releasing a large amount of heat, the radar system of the target flying object will be damaged, causing it to deviate from the preset route and thus ensuring the safety of the ship's navigation.
[0073] Electronic jamming includes frequency hopping and jamming frequency-modulated radar;
[0074] Frequency hopping allows communication signals to jump between different frequencies, making it difficult for the enemy to lock onto and jam them;
[0075] Interfering with frequency-modulated radar: By adjusting the radar's transmission frequency, ships can interfere with the radar system of target aircraft.
[0076] Specifically, by using frequency hopping in conjunction with jamming frequency-modulated radar, the radar system of the target aircraft will be confused, making it impossible for the target aircraft to lock onto the ship. This will cause the target aircraft's flight path to deviate. When the deviation angle is large, there is no need to intercept it, thereby improving the ship's navigation safety and reducing the interception cost.
[0077] Step S5 includes an adaptive filtering algorithm, a motion model, and a target prediction algorithm.
[0078] Adaptive filtering algorithms can adjust and optimize sensor data in real time in dynamic environments, and can respond more flexibly to environmental changes and sensor errors.
[0079] Motion models and target prediction algorithms are introduced, with more complex and accurate target motion models combined with advanced target prediction algorithms to more accurately estimate the future position and state of the target.
[0080] Specifically, by analyzing data such as the surrounding environment, flight speed, and mass of the target flying object, the flight path can be predicted, and the target flying object can be intercepted in advance to ensure the safety of ship navigation.

[0086] Error estimation and correction are used to refine predictions and improve accuracy.
[0087] Output the prediction results, which are the target's location information at a future time point.
[0088] Specifically, the system uses radar, infrared sensors, and other sensors to detect flying objects, analyzing their x, y, and z coordinates, velocity, and acceleration. Based on the target's flight characteristics, such as common motion models like uniform linear motion and accelerated linear motion, a suitable motion model is selected. The target's future position is then calculated using the motion model and current state information. Kalman filters or other error estimation techniques are employed to adapt the model to environmental changes, predict potential errors, correct predictions, and improve accuracy. Sensor orientation is adjusted, or signal compensation parameters are calculated to ensure the system can respond promptly when the target reaches the predicted position. The predicted future target position information is then transmitted to the defense system, adjusting its parameters for more precise interception.
[0089] Step S6 includes field testing and simulation testing;
[0090] Field tests can demonstrate multiple hits on the target aircraft, thereby determining the true information of the target aircraft.
[0091] Simulation testing can detect the electromagnetic signals of a target flying object and compare them with the electromagnetic signals of known flying objects to determine the true information of the target flying object.
[0092] Specifically, through field and simulation tests on flying targets, when multiple detections yield accurate information, the control and defense system intercepts the target. When the target's information is false, its true information is detected, and interception is initiated. This results in high interception accuracy, reduced cost, and enhanced security. If the target's true information is not detected and it has already entered the interception range, interception is performed based on previous information.
[0093] The S8 steps include target identification and tracking, environmental perception and prediction, data processing and optimization, and adaptive system design.
[0094] Target recognition and tracking: Deep learning and neural networks can be used to improve the accuracy and stability of the system in identifying targets.

[0096] Data processing and optimization: Deep learning can be used to optimize the processing and parsing of sensor data, improving the speed and accuracy of data processing and quickly and accurately extracting target information;
[0097] Adaptive system design, utilizing deep reinforcement learning, allows the system to learn and adjust its operating methods to adapt to different environments and threats.
[0098] Specifically, by employing deep learning models such as Convolutional Neural Networks (CNNs), features can be extracted from sensor data to identify and differentiate different types of targets. This can be used for target recognition and tracking, improving the system's accuracy and stability in target identification. Furthermore, by utilizing models such as Recurrent Neural Networks (RNNs) or Long Short-Term Memory Networks (LSTMs), the shipborne system can better understand the dynamic changes in the environment and optimize the processing and analysis of sensor data. This allows the defense system to learn and adjust its operating methods to adapt to different combat environments and threat patterns. Reinforcement learning enables the system to gain experience through interaction with the environment and make better decisions accordingly. Through continuous learning, it can more accurately detect different flying objects and quickly formulate corresponding interception plans, ensuring detection accuracy while increasing flexibility and reducing interception costs.
