FMCW (frequency modulated continuous wave) radar offers several advantages over traditional pulsed radar systems. A major advantage is its ability to provide simultaneous range and speed measurements with high accuracy. This is achieved by continuously transmitting a signal that varies in frequency over time, allowing the FMCW radar to detect both stationary and moving targets and calculate their distance and speed.
Another advantage is its low power consumption and compact size, which makes it suitable for integration into small devices and systems where space and energy efficiency are important factors.
The advantages of FMCW radar include improved resolution and range sensitivity to detect small targets, such as drones or small aircraft, at longer ranges compared to pulsed radar systems. The continuous waveform of FMCW radar allows for better detection and tracking of objects in cluttered environments, where echoes from nearby objects can interfere with signals.
Additionally, FMCW radar provides increased capability to accurately measure target speed, which is valuable for applications such as traffic monitoring, weather radar, and automotive radar systems for adaptive cruise control and collision avoidance.
FMCW altimeters use frequency modulated continuous wave radar technology to measure altitude or height above ground level.
One of the main applications of FMCW altimeters is in aviation and aerospace, where accurate altitude measurement is essential for safe flight operations, particularly during takeoff, landing and navigation in difficult terrain or weather conditions. FMCW altimeters offer advantages such as high accuracy, reliability and the ability to operate in various environmental conditions without being affected by electromagnetic interference or reflections from the terrain. They are also used in unmanned aerial vehicles (UAUs), helicopters and spacecraft for altitude and terrain monitoring
