How to use Power Control to maintain a Constant Flux Density

By: Vineet Kochhar

Given a constant flux density, a transmitter model plugin script can be created to adjust the Transmit Power or EIRP accordingly.

In MATLAB, the code is as follows to compute Power in Watts and convert to dBW:

r2 = range^2;

FD = 1e-7

pow = 10*log10(4*pi*r2*FD);


FD = Flux Density

pow = Transmit Power or EIRP

r2 = range squared

The computed power is assigned to the transmit power in the plugin script.

Sample output is shown here:
