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.

The later return is due to the wave that is re-scattered from a turbine at one edge of the array and is subsequently re-scattered by the turbine on the other edge before returning to the radar resulting in a range delay of 1162 m.
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.
Figure 3 shows a photo of a CVDL-based range delay unit (RDU) built for the US Army MICOM.
Even when operating against pulse tracking radars to interfere with true target range tracking by the radar, it my be sufficient to produce noise at times at and near the true target's range delay time.
With the opening of Auburn Driving Range delayed this spring, golfers have been scrambling to find places to practice.
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.
