"ranging" is the term for detection of the distance between an object and the radar set. today, in our scientific age, it would be difficult to manage without radar. 5. one of the many uses of radar is as a speed control device on highways. when a person in an automobile is driving faster than the speed limit, radar will show this clearly and the traffic police can take measures to stop him. 6. a pilot cannot fly a plane by sight alone. many conditions such as flying at night and landing in dense fog require the pilot to use radar. human eyes are not very good at determining speeds of approaching objects, but radar can show the pilot how fast nearby planes are moving. 23 paragraph 2 . 24 paragraph 3 . 25 paragraph 4 . 26 paragraph 5 . a study of sound b highway police c working principles d early use of "radar" e useful tools f discovery by chance 27 echo-sounding devices were early used to . 28 ultrasonic device were used to . 29 police use radar on highways to . 30 radar helps pilots to . a detect nearby objects b determine the depth of the ocean water c decide how fast you drive d stop passing ships e map the ocean floor f observe water flow   |
