Passage Five
A new kind of radar has been developed
for spaceship travelers. A working laboratory model of a new system of radar
that makes use of a beam of light is said to be ten thousand times more accurate
than the best comparable system of radar that used microwaves.
The model has shown that this radar system, known as laser-doppler radar,
can measure with absolute precision speeds varying from spaceship orbital
injection (进入) velocities (速度) of five miles per second down to virtual
stops—speeds of less than one ten thousandth of an inch per second. According to
the scientists who are developing this system, such fine measures of velocity
are of prime importance in space missions. In a rendezvous (对接) between two
spaceships, or in a landing approach by a vehicle onto an orbiting space
station, a bump could rip open a ship’s skin, or a A. measures the movements of a spaceship by means of light beam B. makes use of microwaves C. makes use of sound waves D. Both A and B
[单项选择]What he has just said has little to do with the question ______ discussion. A. on B. under C. in D. at

The light-beam radar, which operates at a frequency of trillions (百万兆) of cycle A. laser-doppler radar is more accurate than microwave radar B. microwave radar may not ensure absolute precision in measuring varying speeds C. the light-beam radar can measure only slow speeds with accuracy D. microwave radar operates at a higher frequency than laser-doppler radar
