How can I estimate the range of Radar Cross Sections (RCS) for various aircraft and helicopters ? Are there any simple model ?

Hi Tenzing,
I understand that you want to estimate the Radial Cross Sections for various aircrafts and helicopters using kinetic parameters.
You can do that using the empirical formulas that can provide rough estimates based on kinematic parameters.
Here's a simple approach you can use in MATLAB:
% Parameters
speed = 100; % Speed of the aircraft (m/s)
turnRate = 0.1; % Turn rate of the aircraft (rad/s)
range = 5000; % Range from the radar (meters)
wavelength = 0.03; % Wavelength of the radar signal (meters)
% Estimate RCS range
estimatedRCS = estimateRCSRange(speed, turnRate, range, wavelength);
% Display the result
fprintf('Estimated RCS: %.2f m^2\n', estimatedRCS);
Estimated RCS: 3827935392629606318080.00 m^2
function estimatedRCS = estimateRCSRange(speed, turnRate, range, wavelength)
% Constants
Pt = 1e6; % Transmitted power (in Watts)
Gt = 1; % Transmitting antenna gain
Gr = 1; % Receiving antenna gain
% Radar Range Equation with turn rate
estimatedRCS = (Pt * (4 * pi)^3 * range.^4) ./ ((speed + turnRate * range).^2 * Gt * Gr * wavelength^2);
end
Please refer to the below documentation to know more about the Radar equation:
Hope it helps,

@Tenzing Thiley, Flags alert moderators that something needs attention, but it's often not clear what needs to be resolved. You can use comments to address the correctness of an answer. If you suspect an answer to be irrelevant or AI-generated, help us understand your reasoning.
