Fmcw vs pulse radar – difference between cw radar and fmcw radar
CW radar continuously emits a signal at a constant frequency and measures changes in the frequency of the reflected signal to determine the speed of moving objects. It doesn’t measure distance. Pulsed radar, on the other hand, transmits short bursts of energy and measures the delay of the reflected signal to determine distance, and can also provide speed information via Doppler processing.
What is the difference between CW and FMCW radar?
CW radar transmits a continuous signal with a fixed frequency, while FMCW radar varies the frequency of the transmitted signal over time. FMCW radar measures both distance and speed by analyzing the frequency difference between transmitted and received signals, while CW radar only provides speed information through frequency changes.
What is the difference between Pulse Doppler radar and normal radar?
Pulse Doppler radar combines the pulse radar method with Doppler frequency shift measurements to determine both the range and speed of targets. Normal radar usually focuses on measuring distance or speed, but not both simultaneously. Pulse Doppler radar provides detailed target speed information in addition to range.
Moving Target Indicator (MTI) radar uses techniques to filter out stationary clutter and focus on detecting moving targets. Pulse Doppler radar is a type of MTI radar that also measures target speed and range by combining pulse transmission with Doppler processing. The main difference is that MTI radar primarily filters clutter to detect moving targets, while Doppler Pulse radar offers comprehensive speed and distance measurements.
