What is a range Doppler map?

If a transmitter platform is stationary, a range-Doppler map shows a response from stationary targets at zero Doppler. For targets that are moving relative to the transmitter platform, the range-Doppler map shows a response at nonzero Doppler values.

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.
