RASIT is a ground-surveillance pulse Doppler radar developed by Thomson-CSF, and fielded by several militaries. The original version of RASIT had a range of 20 kilometers and allowed a skilled operator to distinguish between personnel, vehicles, and aircraft. RASIT operates in the I band and has a peak power of two kilowatts. The system is deployed on vehicles and has been used by at least 32 nations. The latest version of RASIT, the RASIT-E, has a range of 40 kilometers.
