What are range Doppler maps?
A time-integrated range-Doppler map shows the micro-Doppler characteristics of targets in radar images that enable an operator to classify different target types and to classify different activities being done by the targets.
What is range Doppler algorithm?
RCMC is performed in. range frequency and azimuth frequency domain. Since, azimuth frequency is affected by. Doppler Effect and azimuth frequency is bonded with Doppler frequency, it is called. Range Doppler Algorithm.
What is range Doppler coupling?
Slight Doppler mismatches for the LFM pulse do not change the general shape of the pulse and reduce the amplitude very little, but they do appear to shift the pulse in time. Thus, an uncompensated Doppler shift changes the target's apparent range; this phenomenon is called range-Doppler coupling.
What is range rate in radar?
This velocity is called range-rate. It describes the rate that a target moves toward or away from the radar. A target with no range-rate reflects a frequency near the transmitter frequency and cannot be detected. The classic zero doppler target is one which is on a heading that is tangential to the radar antenna beam.
