3-56. A factor, in determining the maximum and 3-62. 

 minimum range the radar target can be 

 detected and the power of resolution is 

 the 



1. reflected energy 



2. pulse length 



3. energy level of the radar 



4. degree of distinguishing detail 



3-63. 

 3-57. Radar Set AN/FPS-81 is capable of detect- 

 ing a concentration of high moisture 

 content within a maximum radius of how 

 many nautical miles? 



1. 100 nm 



2. 200 nm 



3. 300 nm 



4. 400 nm 3-64. 



3-58. The reason the transmitting portion of the 

 antenna group of the AN/FPS-81 is in the 

 shape of a parabola is to 



1. concentrate the radio frequency 

 energy into a narrow beam 



2. permit the target-reflected energy 



to be received 3-65. 



3. make automatic control of the antenna 

 possible 



4. permit the RTM to be separated from 

 the antenna by a maximum distance 

 of 100 ft 



What should the AG do, if anything, when 

 the antenna of the AN/FPS-106 elevates 

 only to a maximum of 50"? 



1. Adjust the maximum elevation control 



2. Check the down elevation reading 



3. Notify maintenance personnel 



4. Nothing 



What does the AN/GMH-6( ) do? 



1. It records weather information 



2. It checks the output of a PPI scope 



3. It changes the range marks in the 

 AN/FPS-106 scope 



4. It provides a copy printout of 

 weather pictures 



Servicing and maintenance of radar equip- 

 ment in the meteorology spaces is the 

 responsibility of the 



1. electronics personnel 



2. AG3 



3. AG2 



4. AG1 



Working with meteorological radar may be 

 dangerous because of the presence of 



1. X-rays 



2. high voltage 



3. a transmitter 



4. modulators 



3-59. The indicator console houses the RHI , the 

 PPI, and the 



1. RF 



2. RTM 



3. power source 



4. Range Indicator 



3-60. What is the elevation capability of the 

 AN/FPS-106 (V)? 



1. -2° to +60° 3-66. 



2. -3° to +70° 



3. -1° to +40° 



4. -4° to +50° 



3-61. Which component part of the AN/FPS-106 (V) 

 processes the return signal? 



1. Antenna assembly 



2. Control-Indicator 



3. Receiver-Transmitter 



4. Radome 3-67. 



Learning Objective: Identify the 

 different meteorological satellites 

 and the associated ground equipment, 

 conduct operational procedures, 

 and interpret data received. 



Instead of having several separate 

 satellites to gather meteorological 

 information, which of the following 

 systems gathers the information in one 

 satellite? 



1. ITOS 



2. ESSA 



3. TOS 



4 . Nimbus 



The geostationary satellite (SMS/GOES) 

 that orbits over the equator and keeps 

 the same region always in view has an 

 advantage over the polar orbiting 

 satellite because 



1. most of the earth's weather develops 

 over the equator 



2. it views more of the earth's surface 

 on each pass 



3. it can watch the entire life cycle 

 of meteorological phenomena 



4. communications to the tracking 

 station are less garbled
