Instance Code in MATLAB

The following is a simple instance based on how to simulate and process SAR data in MATLAB. The creation of raw SAR data and simple range and azimuth compression are encompassed in this instance:

Step 1: Define SAR Parameters

% Define SAR parameters

fc = 5.3e9;              % Carrier frequency (Hz)

c = 3e8;                 % Speed of light (m/s)

lambda = c / fc;         % Wavelength (m)

prf = 1000;              % Pulse repetition frequency (Hz)

v = 150;                 % Platform velocity (m/s)

r0 = 1000;               % Range to target center (m)

n_pulses = 1024;         % Number of pulses

n_samples = 512;         % Number of samples per pulse

Step 2: Generate Raw SAR Data

% Simulate raw SAR data

raw_data = zeros(n_pulses, n_samples);

for pulse = 1:n_pulses

for sample = 1:n_samples

% Range to target

r = r0 + v * (pulse / prf);

% Time delay

tau = 2 * r / c;

% Simulate radar echo

raw_data(pulse, sample) = exp(-1j * 2 * pi * fc * tau) * exp(-0.5 * (sample – n_samples/2)^2 / (n_samples/10)^2);

end

end

Step 3: Range Compression

% Define range compression filter (matched filter)

range_compression_filter = exp(-0.5 * ((1:n_samples) – n_samples/2).^2 / (n_samples/10).^2);

range_compressed_data = zeros(size(raw_data));

% Apply range compression

for pulse = 1:n_pulses

range_compressed_data(pulse, 🙂 = ifft(fft(raw_data(pulse, :)) .* fft(range_compression_filter));

end

Step 4: Azimuth Compression

% Define azimuth compression filter (Doppler filter)

doppler_filter = exp(-1j * 2 * pi * (0:n_pulses-1)’ * (v / lambda) / prf);

azimuth_compressed_data = zeros(size(range_compressed_data));

% Apply azimuth compression

for sample = 1:n_samples

azimuth_compressed_data(:, sample) = ifft(fft(range_compressed_data(:, sample)) .* doppler_filter);

end

Step 5: Image Formation

% Form the SAR image

sar_image = abs(azimuth_compressed_data);

% Display the SAR image

imagesc(sar_image);
