WebThe aliasing signal is the result of taking these sample values and joining them with a smooth curve. Therefore, the resulting signal has a frequency of half the sampling … WebIn order to avoid this aliasing to happen, what's required is the optical lowpass filtering of the analog image that's formed on the image plane, so that the Fourier transform of the resulting blurry image will be bandlimited to a maximum spatial frequency whose period is at least larger than twice that of the pixel distance of the sensor.

If a Continuous wave radar sends a sine wave at frequency f T to a moving object (at speed V), a frequency f R is received. Their difference is called Doppler frequency and it is equal to f D = f R − f T = − 2 V λ. It is quite clear. Then, it says that the situation is slightly different if a radar which sends ... mynimo free posting
