 Compared to wartime radars like the German FuG 202 and FuG 220 the AI Mk. X has a much wider scanning arc and better range; however does not update instantly, unlike German radars. Compared to the post-war Allied AN/APS-21 search radar, the AI Mk. X has an inferior range and narrower scanning angles but scans much faster.

 The AI Mk. X (Airborne Interception radar, Mark X) is a British version of the American SCR-720 Radar. The SCR-720 was a development of the SCR-520 radar, which was in turn developed using the knowledge gained from the development of the British AI Mk. VIII radar (the first operational microwave-frequency air-to-air radar). The story of the  Airborne Interception (AI) family of radars began in Britain, in late 1935 with the successful testing of the Chain Home system (an early ground-based early warning radar), in which it was proven capable of detecting aircraft at ranges of over 64 km (the range would eventually improve to 160 km). Plans were soon put in place to begin building Chain Home stations along the south coast of England, in preparation for any potential air attack on Britain.
 The chain home system could detect an aircraft at a maximum accuracy of one mile, but it took time to communicate this information to air-crews. The resulting delay between detection and communication to the crews reduced location accuracy to five miles, due to the aircraft moving from the initial reported position. Tracking aircraft would not be a problem for daylight interceptions as fighter pilots could easily spot a plane five miles away, but the reduced accuracy would make the radar system much less effective at night. Henry Tizard, who was leading the implementation of Chain Home, began to fear that the radar system might become too effective. He predicted that if the Luftwaffe ever attacked Britain, it would lead to the Germans suffering enough losses which would force them to switch to nighttime operations, in which case Chain Home would lose its effectiveness. He raised his concerns, and in August 1936 a project was started to develop a radar system which could be fitted onto an aircraft; the plan was that at night Chain Home could guide interceptors to the general area of enemy aircraft, at which point the pilots would switch to using their radars to find the exact location of the enemy aircraft.

 In autumn 1936 the first-ever airborne radar system, known as RDF 1.5 was tested, it consisted of powerful ground-based transmitters and a receiver mounted on a Handley Page Heyford biplane bomber. Although capable of detecting aircraft 80 km away the system was deemed unworkable due to the need for a large number of ground-based transmitters, and having only a very narrow search angle (the transmitter, receiver aircraft and target aircraft needed to be roughly in line with each other). In March 1937, the Heyford was fitted with its transmitter and was able to detect targets a few miles away, and in September 1937 an Avro Anson outfitted with the same radar proved it could be used to identify shipping nearly 10 miles away in poor weather conditions. The rest of 1937 and 1938 refined the radar for ship detection and turning it into a workable system (instead of a battery-powered prototype). In 1939, with the prospect of war becoming inevitable, the focus switched back to detecting aircraft.
