What is Radar Technology?

Radar technology is a remote sensing system that uses radio waves to detect and locate objects. It works by emitting electromagnetic pulses and analyzing the echoes reflected back from targets. The time delay and characteristics of these returned signals provide information about an object's distance, speed, and direction relative to the radar unit.

Discover FMCW

FMCW stands for Frequency-Modulated Continuous-Wave, a cutting-edge radar technology that enables highly accurate, real-time monitoring of vital signs and motion without any contact. This groundbreaking capability opens up a world of possibilities for enhancing patient care, ensuring inmate welfare, and much more.

Today, FMCW is used in a range of applications in aerospace, automotive, defense, and telecommunications. Soon you'll find this technology in smart speakers to enhance audio experiences, TVs to enable gesture controls, and hospitals to anticipate patient decline.

FMCW vs UWB

FMCW and UWB are both advanced radar technologies, but they differ in their approach and capabilities.

FMCW uses frequency modulation to determine range and velocity, allowing for high accuracy and resolution with lower data requirements.

UWB, on the other hand, transmits short pulses over a wide bandwidth, enabling precise location tracking but demanding higher sampling rates and processing power.

	FMCW	UWB
Multi-Target Tracking	Single MIMO device can extract angle of arrival	Requires multiple devices for angle extraction
Data Requirements	Lower sampling rates and processing needs due to bandwidth-reliant target separation	High sampling rates needed for fine target separation, demanding more storage and processing
Vital Sign Extraction	Demonstrates comparable results to UWB in respiratory rate measurement with low error rates	Demonstrates comparable results to FMCW in respiratory rate measurement with low error rates
Indoor Sensing	Single MIMO device can map an area effectively	More prone to transmission/reception error, requires multiple devices to cover the same area
Max Detection Range	Digitally set for increased sensitivity and selectivity	Dependent on pulse width and power
Data Speed & Distance Accuracy	Low data speed and precise distance measurements due to frequency-down-converted beat signals	Requires high data speed to achieve comparable distance accuracy

Key Advantages of FMCW

While both FMCW and UWB are advanced radar technologies, FMCW is the clear choice for vital sign monitoring and indoor sensing applications. FMCW's frequency modulation approach enables superior accuracy and resolution while requiring lower data rates and processing power compared to UWB. This makes FMCW more cost-effective and easier to implement in real-world settings.

Low Data Speed

Our FMCW radars operate at lower sampling rates compared to pulsed radar topologies, thanks to frequency-down-converted beat signals.

Precise Distance

FMCW radars maintain comparable or better range resolution at the same sampling rate.

Adjustable Range

The maximum range of detection for FMCW radars can be set digitally, allowing for the exclusion of further objects from the sensing setup.

Coexistence Capabilities

Continuous waveform radar reduces interference with nearby transceivers, as each occupies a specific frequency.
