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 are the 3 types of radar?

Monostatic, Bistatic and Multistatic

In a bistatic radar, the transmitter and receiver are separated by a distance similar to the expected target distance (Figure 2). A system that includes multiple spatially distributed monostatic or bistatic radar elements covering a common area is called multistatic radar.

What is a Doppler signal?

Sheps, M.D. A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.

What is Doppler FFT?

FFT Plot (Range-Doppler Plot): The FFT is used to convert radar time domain data to frequency domain. Detected objects and their Doppler signature are plotted in an FFT Plot. The x-axis represents the Doppler Frequency (which can be converted to Doppler Speed), and the y-axis is range.
