The AN/SPN-46 Automatic Carrier Landing System (ACLS) is an Ka-band and X-band monopulse doppler Precision Approach Landing System (PALS). Developed by Bell Textron, it is manufactured in the United States by Textron Systems. The radar uses two dual-band radar antennas to guide fixed-wing aircraft or helicopters to landing in all-weather conditions with no limitations due to low ceiling or restricted visibility.
