意を喚起するものである。 As is well known, various air traffic control systems using secondary surveillance radars have been developed. The proximity altitude warning processing device determines whether the altitude of the aircraft is within the danger range by using the altitude information from the secondary monitoring radar, for example in response to a mode C beacon, and if it is within the danger range, issues a warning and alerts the aircraft. This is to alert the air traffic controller.

高度等の情報が表示される。 FIG. 1 shows a secondary surveillance radar to which the present invention is applied, and 11 is a mode pulse generator that generates an interrogation code. For example, mode C and 3/A pulses output from this generator 11 are supplied to a transceiver 12. The transceiver 12 supplies the transmission signal to an interrogation antenna 14 installed on the primary surveillance radar 13, and transmits the interrogation signal to the aircraft from the interrogation antenna 14. A response signal from the aircraft is captured by the interrogation antenna 14 and supplied to a digitizer (target detection device) 15 via the transceiver 12. The digitizer 15 analyzes the response signal and outputs the altitude, identification code, and position information of the aircraft. These pieces of information are supplied to the arithmetic processor 16, which calculates the predicted position of the aircraft and performs tracking processing. The output information of the arithmetic processor 16 is supplied to the display device 17, and the aircraft tracking mark and the corresponding aircraft identification code are displayed on the display screen.
Information such as altitude is displayed.

る。 On the other hand, the arithmetic processor 16 stores a warning altitude range in advance. As shown in Figure 2a, this warning altitude range is the coverage area of the secondary surveillance radar (the coverage area of the electromagnetic waves sent from the interrogation antenna 14) of n nautical miles on each side (n is the processing speed of the processing unit and the required calculation accuracy). It is divided into squares (arbitrarily set according to , A1, A2 are attached. For example, condition A0 means no warning in the altitude range of 500 to 1500 feet, A1 requires warning in the altitude range of 0 to 500 feet, and A2 requires warning in the altitude range of 1500 to 2000 feet or 6000 to 8000 feet. Further, the processing in the arithmetic processor 16 is performed using a quadrangular prism as one unit. That is, first, the processor 16 determines the current position and predicted position of the aircraft subject to altitude warning processing from the information supplied from the digitizer 15, and determines the corresponding altitude warning processing unit. Next, the warning altitude condition assigned to the determined altitude warning processing unit is compared with the current altitude of the aircraft, and if an altitude warning is necessary, an alarm generating means such as a buzzer 18 is used to call the controller's attention. is activated and an alarm is issued.
At the same time, the display of the warning target aircraft on the display device 17 is flashed, for example, to distinguish it from other aircraft.

航空管制を行なうことが可能である。 In this way, by representing the altitude warning range as a rectangular prism with a square base of n nautical miles on a side, and processing this rectangular prism as one unit, altitude warning processing is extremely simple compared to the conventional method. Can be done at speed. Therefore, it is possible to perform quick and accurate air traffic control.
