We have picked up radar emissions from a surface contact. Contacts will automatically be classified by the AI according to matching emissions in the database. With ESM contacts it is common to have an 'area of uncertainty' around the contact, which is dependent on the strength of the detected emission, capability of the receiving set and information coming from other platforms.

Since ESM is a passive detection method that only indicates the existence of an emitter in a particular area, it does not give exact position information nor speed, altitude or heading information. You may be able to get very accurate positions, however, by moving two units with ESM sets into positions where they can both detect the ESM contact and triangulate the position of the contact.

You can see more information about which precise sensors on your platforms are detecting or tracking a contact by clicking on the contact's map symbol and observing the 'Last Detections' column in the right-hand side status bar.

Try clicking on the hyperlinks in the Last Detections column to see more information about your detected contacts and the sensors that are tracking them.

If you haven't done so already, make sure the helicopter radar is switched on (F9).
