K-LC6 RADAR TRANSCEIVER

Datasheet

Sensitivity and Maximum Range

The values indicated here are intended to give you a 'feeling' of the attainable detection range with this

module. It is not possible to define an exact RCS (radar cross section) value of real objects because

reflectivity depends on many parameters. The RCS variations however influence the maximum range

Maximum range for Doppler movement depends mainly on:

- Module sensitivity

S:

-126dBc (@1kHz IF Bandwidth)

- Carrier frequency

24.125GHz

- Radar cross section RCS ("reflectivity") of the object

The famous "Radar Equation" may be reduced for our K-band module to the following relation:

Using this formula, you get an indicative detection range of

- > 24 meters for a moving person

- > 62 meters for a moving car

Please note, that range values also highly depend on the performance of signal processing,

environment conditions (i.e. rain, fog), housing of the module and other factors.

With K-LC6, you can achieve a maximum range of more than 100m when using high resolution AD-

converters and selective FFT algorithms.
