Richard John The working principle of continuous wave (CW) Doppler radar involves transmitting a continuous radio frequency signal and analyzing the frequency shift of the reflected signal caused by the movement of a target. The Doppler effect causes the frequency of the reflected signal to change if the target moves. By measuring this frequency shift, the radar … Read more

The Doppler method of radar involves using the Doppler effect to measure the speed of a moving target. It works by emitting a signal and analyzing the frequency shift of the reflected signal caused by the movement of the target. This frequency shift, or Doppler shift, allows the radar to determine the speed and direction … Read more

Radar target resolution refers to the ability of the radar system to distinguish between two or more spaced or more widely spaced objects. It is determined by factors such as pulse width, frequency and antenna characteristics. Higher resolution allows better discrimination between targets that are close to each other. The range of a radar target … Read more
This article presents about What is the Doppler spectrum?, What is the Doppler effect spectrum?, What is the spectral Doppler? What is the Doppler spectrum? The Doppler spectrum refers to the range of frequencies resulting from the Doppler effect when a moving object reflects a radar signal. It represents the shift in frequency of the … Read more
The use of a sideband filter in continuous wave (CW) radar is to isolate the Doppler shift frequencies which are essential for detecting the speed of moving targets. By filtering out unwanted frequencies and focusing on the frequency shift introduced by target movement, the sideband filter helps accurately measure Doppler shift and, therefore, target velocity. … Read more
Ready to learn more about What is the frequency of the Doppler radar?, What is the frequency of the Doppler sensor?, What is the Doppler frequency rate? What is the frequency of the Doppler radar? The frequency of Doppler radar generally depends on its application. For weather radar, it is usually in the S-band (2 … Read more
The main limitation of continuous wave (CW) radar is its inability to measure the range of a target. The CW radar continuously emits a signal and measures the Doppler shift of the reflected signal to detect movement and determine speed. However, because it does not send discrete pulses, it cannot measure the delay between signal … Read more
