Hi Abdul,
To create a dataset for predicting RF ray properties after interactions in MATLAB, you can simulate the path of RF rays using ray tracing techniques. Utilizing tools like the raytrace function in the Phased Array System Toolbox for ray tracing simulations to define the scenario, including the transmitter, receiver, and objects in the environment. Now, to capture the properties of each ray at interaction points, you need to intercept the rays when they hit an obstacle or bounce off a material. You can extract information such as, Incident angle, Reflection angle, Path loss,Phase shift, Polarization change and Material properties at the interaction point. Afterwords, Iterate through the simulation results and record the properties of each ray at interaction events. Store this information in a structured format like a table or a dataset in MATLAB. Ensure to include all relevant properties for training your AI model.Here's a simplified example to demonstrate how you can extract and store ray properties during simulation:
% Perform ray tracing simulation
% Assume 'rayPaths' contains information about ray paths
rayProperties = struct('IncidentAngle', [], 'ReflectionAngle', [], 'PathLoss', []);
for i = 1:numel(rayPaths)
% Extract properties at interaction points rayProperties(i).IncidentAngle = rayPaths(i).incidentAngle; rayProperties(i).ReflectionAngle = rayPaths(i).reflectionAngle; rayProperties(i).PathLoss = rayPaths(i).pathLoss; % Add more properties as needed
end
% Create a dataset from extracted properties
rayDataset = struct2table(rayProperties);
Once you have collected the ray properties data, preprocess it as needed for training your AI model. Then, split the dataset into training and testing sets, normalize the features, and handle any missing values. If you follow these steps, you can create a comprehensive dataset containing the properties of RF rays at interaction points, enabling you to train your AI model effectively for predicting RF ray behavior after interactions with objects.
