In general sensor operations requires an Intelligence + Sciences (Sensor Operations) roll. When doing scans for pirates or other ships, a scan adding the sensor rating of the ship, and subtracting any stealth rating of the ship(s) beening sought. 

If you are scanning an entire system for a specific object, the sensor operation becomes an extended action, requiring a number of success which depends upon the size of the object being sought. Scanning a planetary surface to make a map or find specific objects also requires a extended sensor scan. Each roll takes about an hour to perform.
