{{Note| EM.Terrano receivers, by default, are defined as isotropic or polarization-matched radiators.}}
If you want directional radiators for your receiver set, you need to open the Receiver dialog by right-clicking on the receiver set's name in the navigation tree and opening its property dialog from the contextual menu. In the "Radiator Properties" section of this dialog, select the '''User Defined''' radio button. Similar to the case of transmitter set, you can import a '''.RAD''' radiation pattern file using the {{key|Import PaternPattern}} button. You can also rotate the imported radiation pattern by setting '''Rotation Angles''' different than the default zero values.
EM.Terrano allows you to define a basic '''Heterodyne Receiver Chain'''. Click the {{key|Receiver Chain}} button of the Receiver Set dialog to open the Receiver Chain dialog. As shown in the figure below, you can specify the characteristics of the Low-Noise Amplifier (LNA), mixer and baseband/IF amplifier including stage gains and impedance mismatch factors (IMF) as well as the characteristics of the transmission line segment that connects the antenna to the LNA. Note that the receiving antenna characteristics are automatically filled from using contents of the radiation file. You have to enter values for antenna's '''Brightness Temperature''' as well as the temperature of the transmission line and the receiver's ambient temperature. The effective '''Receiver Bandwidth''' is assumed to be 100MHz, which you can change for the purpose of noise calculations. You also need to enter values for the '''Noise Figure''' of various active devices in the receiver chain. The Receive Chain dialog also calculates and reports the "Noise Power" and "Total Receiver Chain Gain" based on your input.
In the Receiver Set dialog, there is a dropdown list labeled "Selected Receiver", which contains a list of all the individual receivers belonging to the receiver set. At the end of an SBR simulation, the receiver power and signal-noise ratio (SNR) of the selected receiver are calculated and reported in dBm and dB, respectively. The {{key|Show Ray Data}} button also allows you to see the details of all the received rays by the selected receiver.
