radar echo การใช้

• Consequently, a non-coherent radar echo contains less information about the sea surface properties.
• Two hours later, another radar echo was picked up, away.
• Zaitsev observed the asteroid 4179 Toutatis in December 1992 using the 70-m radar echo.
• It was during this investigation that Dr Fujita discovered the " bow " or " spearhead radar echo ".
• The radar proved most accurate in coastal regions, as the water surface and the coastline produced a distinctive radar echo.
• He then went back and looked at the radar echos, and he noticed that they evolved into a bow signature.
• Meteorologists from Texas A & M concluded that the radar echo could serve as advance warning of a pending tornado event.
• The pilot was informed of a new radar echo, which indicated that another object might be near Sagunto ( Valencia ).
• In 1968, Goldstein was the first to obtain a radar echo from an asteroid, when he measured the radar cross section of Icarus.
• Measurements on the mass balance of the glacier, as well as more detailed ice thickness measurements using a portable radar echo sounder, were undertaken.
• In 1964, Goldstein had analyzed the spectrum of radar echos from Venus to obtain the first images of features on the surface of that planet.
• Typical evolution of a thunderstorm radar echo ( a ) into a bow echo ( b, c ) and into a comma echo ( d ).
• The Civil Guard Maritime Service from this southern Spanish town detected the radar echo of a small boat in the Straits of Gibraltar soon after midnight.
• In the second attack, the destroyer's guns fired for five minutes as she pursued her target until its radar echo merged with land echo of Kiska.
• Smith said published data on radar echo observations of Titan taken from Earth indicated a large, bright region that appeared to coincide with the Hubble images.
• The Civil Guard Maritime Service from the southern Spanish town of Algeciras detected the radar echo of a small boat in the Straits of Gibraltar soon after midnight.
• As a graduate student at Caltech in 1961, Goldstein used the antenna at the Goldstone Tracking Station to obtain the first realtime radar echos from the planet Venus.
• However, when the radar is transmitting, the device cannot receive radar echo, thus the radar can only receive a signal from targets that are included within PRI-2 \ tau.
• With radar, relative distance measurements ( by timing of the radar echo ) and relative velocity measurements ( by measuring the doppler effect of the radar echo ) are possible.
