ELEMENTS OF REMOTE SENSING QUIZ

All of these

Constant solar zenith angles and similar illumination conditions

Synoptic view of a large area

Repetitive observations of the same area with intervals of a few minutes to a few weeks

Signal propagation biases due to the sphere and troposphere propagation

All listed here

Receiver-dependent biases due to clock stability with line

Satellite dependent biases due to uncertainty in the orbital parameters of the satellite

The oscillation of charged particles sets up changing electric fields

The changing electric fields induce the changing magnetic fields in the surrounding medium

These are produced by the motion of electric charge

None of these
