How does Doppler effect play a role in radar technology?

• Radar technology uses Doppler effect to measure temperature

• Doppler effect in radar technology is used to detect static objects

• Doppler effect is used in radar technology to measure the velocity of moving objects by analyzing the frequency shift of the reflected radar waves.

• Doppler effect is not used in radar technology

Discuss the importance of radar cross section in radar detection.

• Radar cross section only affects visual detection, not radar detection

• Radar cross section is only important for detecting stationary objects

• Radar cross section is important in radar detection because it determines the detectability of an object by radar. A larger radar cross section makes an object more easily detectable, while a smaller radar cross section makes it harder to detect.

• Radar cross section has no impact on radar detection

Making repeat exposures with the same radiographic technique should result in constant radiation output intensity:

• Linearity

• mA Accuracy

• Reproducibility

• kV Accuracy
