IWR1642BOOST: Sensor Basics

Prodigy 10 points
Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, IWR6843, IWR6843ISK, IWR6843ISK-ODS, MMWAVEICBOOST

Hello, I have a bunch of random questions about the IWR 1642 Boost, some of them are probably pretty straightforward, but my co-workers and I are not well versed with this kind of technology.
It might help if I give you a little background information about our research and what our goal is: 
So we are wanting to use mmwave sensors in an outdoor setting for a continuous and extended period of time (a month or so) to track human movement through university landscapes. We are going to partner with another department at our university that will collect that data from our sensors through a campus 5G network using drones. Our hope is to then take this data and georeference it in ArcGIS.
We have already ordered a IWR1642 Boost sensor, and have done a little playing around with it. There are some things that we are struggling with, primarily because this is something that is completely new to all of us:
-Is there a way to house sensors in a safe way outdoors? If so, are there any recommendations? Could it be 3D printed?
-Is a power source (battery) that can be used, or does it have to continuously be connected to a computer/outlet? How long could this battery last?
-How much data storage is capable? Do we have to develop our own software to log the data, or is there a basic program already available?
Thanks!

    Hello,

      From regulatory perspective you may want to explore IWR6843 devices for tracking human movements using fixed installations. IWR6843ISK or IWR6843ISK-ODS EVMs along with mmWaveICBOOST hardware. 

    1) For housing you may need to develop Radome. There are guideline you need to follow thickness, distance to Antenna and choice of material for the Radome to get optimal performance. Please refer to below application note.

    2) You could use the battery source, AA or AAA kind of battery may not be sufficient, you may need larger size battery for operating longer hours 5000 mAh or 10000mAh kind of rechargeable battery  could be used for this purpose. Also battery time would be dependent on type of chirp configuration, Frame rate, duty-cycle etc. You may want to experiment on this depending upon your application and arrive at the right battery capacity and duration needed. 

    3) For data storage, it depends upon what type of data that you want to store. If you need to store the raw ADC data (through high speed LVDS interface) then several Gigabytes of storage may be needed. DCA1000 + mmWave studio provides option to store the raw data into external PC hard-disc via Ethernet interface. Alternatively, you could store the processed data (Objects, Range, Velocity, Angle) information sent over UART port to external host or processors. This size would be much smaller, However you need to develop your own data logging mechanism. You may visit mmWave visualizer (https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.3.0/ ) for recording the processed data.

    Thanks and regards,
