8 / 8 page K-MC3 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 only by 4 . Maximum range for Doppler movement depends mainly on: - Module sensitivity S: -145dBc (@1kHz IF Bandwidth) - Carrier frequency f0: 24.125GHz - Radar cross section RCS ("reflectivity") of the object 1): 1m2 approx. for a moving person >50m2 for a moving car note 1) 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: 4 40 10 0167 . 0 s r Using this formula, you get an indicative detection range of - > 70 meters for a moving person - > 180 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-MC3, you can achieve a maximum range of more than 500m when using high resolution AD- converters and selective FFT algorithms.
