3 Radar can control moon probes to soft landings.
4 Radar can map out ground areas from the air and measure the
depth of land contours beneath the ice in Greenland and Antarctica.
(b) Civilian uses.
1 Radar is used to monitor commercial aircraft for safe air traffic
2 Radar is used to hunt out weather disturbances by spotting
3 More recently, radar is used in stores to detect shoplifters. All
store items have radar detectable markers.
4 Familiar to us all, radar is used by the police to monitor the
speed at which we are driving.

c. Power Transmission. It is possible that future generations may get power
for their needs via microwaves. One advantage would be that microwave transmission
(the power) would take place through waveguides which would look like large insulated
water pipes. Less power would be lost than is now lost when power is transmitted over
high-voltage power cables. To date, it is still inefficient to convert microwave energy to
d. Microwave Spectroscopy. A microwave spectroscope is a tool used in
basic research to examine the internal structure of materials in the same way x-radiation
