## Compute Peak Power Using Radar Equation Calculator App

The `radarEquationCalculator` App lets you determine key radar characteristics such as detection range, required peak transmit power, and SNR. The App works for monostatic and bistatic radars.

### Open radarEquationCalculator App

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.

`radarEquationCalculator` ### Compute Required Peak Transmit Power of Monostatic Radar

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.

1. From the Calculation Type drop-down list, choose `Peak Transmit Power`

2. Set the Wavelength to `3` cm

3. Specify the Pulse Width as `2` microseconds

4. Assume total System Losses of 5 dB

5. Assuming the target is a large airplane, set Target Radar Cross Section value to 100 m2

6. Choose Configuration as `Monostatic`

7. Set the Gain to be `40` dB

8. Open the SNR box

9. Specify the Probability of Detections as `0.9`

10. Specify the Probability of False Alarm as `0.0001`

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.
