In Japan, today's congestion of aircraft in important airports is very serious. The method and equipment to solve this congestion problem and to decrease the task load of tower controllers are required. We then had proposed a system for the airport surface surveillance by using the conventional SSR (Secondary Surveillance Radar) and cross-correlation method for the suppression of garble among the SSR replies. In this paper we show the new system for the airport surface surveillance. In this new system it will be expected that the system will realize its very high performance since the algorithm of signal processing is much improved by using the position data of the aircraft produced by ASDE (Airport Surface Detection Equipment). And the prototype of the console of this system realized on the engineering workstation is also shown and the capability of this system is discussed.
