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
only by
4
.
Maximum range for Doppler movement depends mainly on:
- Module sensitivity S: -140dBc (@1kHz IF Bandwidth)
- Carrier frequency f
0
: 24.125GHz
- Radar cross section RCS ("reflectivity") of the object

: 1m

RCS indications are very inaccurate and may vary by factors of 10 and more.
The famous "Radar Equation" may be reduced for our K-band module to the following relation:

s
r
Using this formula, you get an indicative detection range of
> 50 meters for a moving person
> 140 meters for a moving car
Please note, that range values also highly depend on the performance of signal processing,
environment conditions (i.e. rain), housing of the module and other factors.
