range delay

range delay

[′rānj di‚lā]
(electromagnetism)
A control used in radars which permits the operator to present on the radarscope only those echoes from targets which lie beyond a certain distance from the radar; by using range delay, undesired echoes from nearby targets may be eliminated while the indicator range is increased.

Channel effects include smooth, phase-continuous carrier and signal Doppler shift, range delay, range attenuation, fading, and noise.
In addition, STK sets up the T400CS so it that can produce exact range delay, Doppler shift, range attenuation, AWGN (additive white Gaussian noise), and fading for the specified scenario.
Ionosphere correction models are required to correct the time delay or its equivalent range delay introduced by the ionosphere.
An ionosphere model to be used operationally to correct the range delay should have the following main characteristics:

For example, if an airplane flying over a humvee was transmitting signals to the ground, the link would be affected by high Doppler shift rates and varying range delays that the humvee's receiver would need to track.
