1 ASSIGNMENT 1 Textbook assignment:  Chapter 1, “Radar Fundamentals,” pages 1-1 through 1-45. ___________________________________________________________________________________ 1-1.   Radar uses what form of energy to detect ships, planes, and land masses? 1.    Sound waves 2.    Visible light 3.    Infrared radiation 4.    Electromagnetic energy 1-2.   What radar measurement of an object is referenced to true north? 1.    Height 2.    Surface angle 3.    Vertical angle 4.    One-way distance 1-3.   The elevation angle to the target is the angle between which of the following references? 1.    Ship's heading and line of sight 2.    Vertical plane and line of sight 3.    Horizontal plane and line of sight 4.    Vertical plane and horizontal plane 1-4.   Electromagnetic energy travels through air at approximately what speed? 1.           984 feet per microsecond 2.    186,000 statute miles per second 3.    162,000 nautical miles per second 4.    Each of the above is correct 1-5.   For an object that is detected 15 miles from a radar set, what is the approximate time required for the rf energy to travel to and return from the object? 1.        7 microseconds 2.    185 microseconds 3.    271 microseconds 4.    927 microseconds 1-6.   The minimum range of a radar depends on the length of time of the transmitter pulse (pulse width) and recovery time. During this period, the radar can NOT receive energy.  A radar set with a pulse width of 5 microseconds and a recovery time of 0. 2 microseconds has a minimum range of approximately 1.       614 yards 2.       787 yards 3.       852 yards 4.    4,100 yards 1-7.   Of the following radar characteristics, which has NO effect on maximum range capability? 1.    Recovery time 2.    Carrier frequency 3.    Receiver sensitivity 4.    Pulse-repetition frequency 1-8.   Which of the following characteristics of a radar system determines the degree to which the radiated energy is affected by atmospheric conditions? 1.    Pulse peak power 2.    Carrier frequency 3.    Receiver sensitivity 4.    Pulse-repetition frequency 1-9.   Pulse-repetition time is described as the 1.    reciprocal of pulse width 2.    period of time from the beginning to the end of a transmitter pulse 3.    period of time required for the pulse to travel to the target and return 4.    period of time from the beginning of one transmitter pulse to the beginning of the next
