Thus, I get a maximum range double the one in the example, i.e. around 2.96 meters. Splitting them into 64 range bins equals a range bin size of around 4.64 cm. Now, I am recording while the radar has a distance of around 1.2-1.3 meters from the chest. The plot below shows the ...

Before deciding on the frequency of operation or the specific radar topology to be used, it is useful to first deduce some parameters of the object(s) that the radar should be able to detect. Size and material Maximum range Maximum velocity Proximity to other objects The amount of information...
The sizes of the various dimensions are chosen based on the required range, speed, and direction parameters. We use the following typical system parameters: λ = 3.9mm, corresponding to 77GHz radar B = 300MHz, the bandwidth sweep of one chirp Tʄ = 10µs Range maximum = 500m, ...

This bistatic FMCW radar delivers continuous information on the distribution and thickness of cloud layers, permitting accurate determination of the cloud base altitude and upper limit. The maximum range is 16 km, with a corresponding resolution of 30 m: both range and averaging time are user ...

3 FMCW RADAR Digital Signal Processing Let's now focus on range estimation. The maximum range the RADAR chip detects depends on the application. But what is behind the maximum range equation? Let's look into this by taking the example of presence detection. Whether you mount the RADAR ...
F ≥ s c An ADC sampling rate of Fs limits the maximum range of the radar to F c d = s max 2S 15 Question • Revisiting our earlier example, what more can we now say about these two chirps? Chirp A Chirp B f f While both Chirp A and B have the same range resolution: •...
