CCS/AWR1843BOOST: The difference between the two Tx antennas and three Tx antennas configuration for the beamforming mode

Rata Zhang

Part Number: AWR1843BOOST

Tool/software: Code Composer Studio

Hi,

For the AWR1843BOOST, in the beamforming mode, three Tx antennas (including one elevation and two azimuth ones)can be used to forming the boeam. Now I just want to use the two azimuth antennas for the beamforming mode.If I use this configuration, will the max detectable range be nearer than three antennas condition? Will the intensity of the echo signal be weaker than three antennas condition?If only two azmuth antennas are used, the ground clutter will be removed, that is to say, only the objects that are the same level with the radar can be detected, is that right？

Thanks，

Regards,

With 2TX the maximum detected range should be smaller than with 3TX.

Please perform experiments.

Thank you

Hi Cesar，

Thanks for your reply, if only the 2 azimuth Txs are used, the objects that are on the same level be detected, is that right?

You will also detect objects which are not at same level but you will not have elevation information.

Since all the information will be included in azimuth plane.

Thank you
