<p>PROBLEM TO BE SOLVED: To provide an airplane recognizing and detecting device which securely detects the airplane, by recognizing an object on its track by using a high-frequency radar. SOLUTION: The device consists of a transmission part 1 which radiates a microwave to a track area of an airplane from a transmitting antenna 15; a reception part 2 which receives a reflected wave of the microwave by a receiving antenna 21 and generates image information by a mixer 22, an amplifier 23, and a demodulating process circuit 24; an image processing part 3 which converts the image signal from the reception part 2 from analog to digital, erases an image of a fixed target by an eraser 32 to extract an image of a moving target, then recognizes an image of the airplane, and finds data on speed, etc., by an arithmetic circuit 33 on the basis of the image of the airplane; a communication part 4 which transmits are information processed by the image processing part 3 to a control tower, etc.; and a display part 5 which displays image data on the airplane and data on the speed, etc. The radio wave radiated by the transmitting means is reflected and scattered by a object in its radio wave radiated area and part of the reflected wave arrives at the receiving means and is received, thereby generating image information regarding the radio wave radiated area.</p> |
