K-MC4 MONOPULSE RADAR TRANSCEIVER Datasheet

Sampling Requirements

Using RSW requires sampling of the IF signals during the active enable time. Normally, AD conversion

and asserting /Enable signal on K-MC4 must be synchronized.

If the ADC contains a sample-and-hold (S&H) device, sampling command can be fired at the end of

the /Enable signal. Enable time t

must be > 5µs or > setup time of the S&H, whatever value is

higher.

If the ADC does not contain a S&H input stage, conversion command should be issued at the very

beginning of the enable period. Enable time t

must be > 5µs or > 1/bandwidth of the ADC, whatever

value is higher.

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



Maximum range for Doppler movement depends mainly on:

- Module sensitivity S: -134dBc (@1kHz IF Bandwidth)

- Carrier frequency f

: 24.125GHz

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

: 1m

approx. for a moving person

>50m

for a moving car

note

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:

100167.0





s

Using this formula, you get an indicative detection range of

- > 37 meters for a moving person

- > 93 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), hoµsing of the module and other factors.

With K-MC3, you can achieve a maximum range of more than 500m when µsing high resolution AD-

converters and selective FFT algorithms.
