WebMay 25, 2024 · With moving targets, the frequency of a spike is dependant on a combination of the radial velocity and range. With FMCW radar you are always measuring velocity as well, even when you'd rather not. This is because the doppler shift interferes with the distance-induced frequency difference being measured. The frequency offset due to the … WebFeb 19, 2024 · $\begingroup$ As it sounds like you are asking, to confirm yes indeed the product of two signals occupying specific frequencies (tones) would be the sum and the difference. We see this in the trigonometric product identities such as $\cos(\alpha)\cos(\beta) = \frac{1}{2}cos(\alpha+\beta) + \frac{1}{2}cos(\alpha-\beta)$ …

WebJun 6, 2024 · Multiple target detection using FMCW Radar. Dear All, I have written a code in MATLAB to determine the range of target for FMCW Radar. The code correctly determines the range of a single static target. I now want to increase the number of targets. Currently, I am just focusing on the range of targets without considering any doppler.

WebThe Hanning window is defined as. w(n) = 0.5 − 0.5cos( 2πn M − 1) 0 ≤ n ≤ M − 1. The Hanning was named for Julius von Hann, an Austrian meteorologist. It is also known as the Cosine Bell. Some authors prefer that it be called a Hann window, to help avoid confusion with the very similar Hamming window. Most references to the Hanning ...
