How do you compute received power for a volumetric analysis?

This quick example describes how to define airspace around a ship emitter and compute received power at each grid point in that airspace by using Spatial Analysis in STK.

1. Create a ship () with a complex transmitter ().
2. Define the antenna pattern.
3. Create an area target () around the ship and use the area target to define the AirSpace volume.

Create an Aircraft with a Receiver

1. Create an aircraft ().
2. Attach a receiver () to the aircraft. The receiver will define the receiver on each of the airspace grid points. The position of the aircraft does not get used when populating the grid points of the airspace.

Create an Aircraft with a Receiver

1. Compute access between the aircraft receiver and the ship transmitter

Use Analysis Workbench to Create a Scalar Calculation

1. Using Analysis Workbench (), create a Data Element type Scalar Calculation on the access object.
2. Open the Link Information Data Provider and assign the Received Isotropic Power or Carrier Power at Receiver Input.
3. On the receiver object, create a spatial calculation of type Scalar At Location based on the Received Power scalar calculation.

Create a Volumetric Object

1. Create a Volumetric object ().
2. Use the AirSpace () to define the Volume Grid and use the Received Power Spatial Calculation for the Spatial Calculation.
3. Open Airspace's () properties.
4. Select the 3D Graphics - Volume properties to display the Spatial Calculation levels.
