Hi Julius,
As per my understanding, you want to create an additional interfered signal to use the signals to create a neural network for denoising.
An interfering signal can be another radar signal, potentially with different parameters (e.g., different chirp slope, initial frequency, etc.), or it could be more arbitrary noise. For simplicity, let's assume you want to simulate interference from another radar with slightly different parameters.
Once you have both signals, you need to combine them. This could be as simple as adding the two signals together, potentially with some scaling if one signal is supposed to be weaker than the other.
Please refer to the code snippet below:
% Parameters for the interfering signal (example values, adjust as needed)
interferingSlope = 2.0e12; % Different chirp slope for the interfering signal
interferingInitialFrequency = 77e9; % Initial frequency
interferingSampleRate = 1e6; % Sample rate
interferingPulseRepetitionFrequency = 5e3; % Pulse repetition frequency
interferingNumSamples = numel(originalSignal); % Number of samples
% Generate the interfering signal (simplified example)
t = (0:interferingNumSamples-1) / interferingSampleRate;
interferingSignal = cos(2 * pi * (interferingInitialFrequency * t + 0.5 * interferingSlope * t.^2));
% Combine the original and interfering signals
combinedSignal = originalSignal + interferingSignal;
% Proceed with processing the combinedSignal as needed
I hope this helps!
