radarEquationCalculator is a Matlab™ App that lets you determine key radar characteristics such as detection range, required peak transmit power, and SNR. The App works for monostatic and bistatic radars.
When you type
radarEquationCalculator from the command line or select the app from the App Toolstrip, an interactive window opens. The default window shows a calculation of target range from SNR, power, and other parameters. You can then select various options to compute different radar parameters.
As an example, use the app to compute the required peak transmit power for a monostatic radar to detect a large target at 100 km. The radar operates at 10 GHz with a 40 dB antenna gain. Set the probability of detection to 0.9 and the probability of false alarm to 0.0001.
From the Calculation Type drop-down list, choose
Peak Transmit Power
Set the Wavelength to
Specify the Pulse Width as
Assume total System Losses of 5 dB
Assuming the target is a large airplane, set Target Radar Cross Section value to 100 m2
Choose Configuration as
Set the Gain to be
Open the SNR box
Specify the Probability of Detections as
Specify the Probability of False Alarm as
Close the App window. Normally, you close the App using the close button.
hg = findall(0,'Name','Radar Equation Calculator'); close(hg)
You can see from this previously prepared screen shot that the required peak transmit power is .2095 W.
