IWR1642BOOST: Can this evaluation board using mmWave Sensor technology be used for accurately detecting occupancy states...
Part Number: IWR1642BOOST
There were some pilot projects carried out in Berlin by Siemens using Radar sensors. The issue that they faced was that when low density objects such as leaves or awning were swept across the parking spot by wind, a false detection of occupancy was made by the radar sensor.
My question is that will IWR1843BOOST EVM be immune to such disturbances in order to prevent false detection of occupancy of parking spots?
As explained in this video by TI: https://www.youtube.com/watch?v=B3R-3rzmzXU&t=51s
The sensor is placed at a height of 14 feet above the ground and the view seen by the sensor is shown below:
As can be seen from the right hand side of the image, the sensor is able to detect more than 60 parking spots. I counted it from the while lines. Is it possible for a single IWR1843 mmWave radar sensor to detect occupancy status of around 60 parking spots when placed at a height of 14 feet above the ground?
Can the IWR1843BOOST EVM be also used for indoor parking spot occupancy detection as shown below in addition to outdoor parking spot detection? The IWR1843BOOST EVM will be mounted on the roof ceiling facing downwards and the height of the roof is around 8 feet. There will also be pillars as shown in the below picture:
Thanks and Regards,
Please refer to the traffic monitoring TI Design which gives you some more information about the mounting height and angle to determine the sensor area coverage: http://www.ti.com/tool/TIDEP-0090
Also refer to the antenna database to understand the FoV of the antenna: http://dev.ti.com/tirex/explore/node?node=AKu-aTm5FIcxlwZJU1pLBw__VLyFKFf__LATEST. You should be able to calculate the expected area coverage given your desired mounting height and sensor orientation.
Using the gtrack algorithm, filtering out movement from leaves and fluttering objects can be done. An example is demonstrated here: http://dev.ti.com/tirex/explore/node?node=AMn8XKVsX657Env-K6JAQg__VLyFKFf__LATEST
We have not used 1843 specifically for parking spot detection however it should be achievable to some extent. The number of cars and the variation from outdoor to indoor garage scenarios would require development and testing for your applicatino. I would also recommend you look at the area scanner demo which could also be a relevant starting point: http://dev.ti.com/tirex/explore/node?node=AD6F02XtKZMeXTYUwLQKMw__VLyFKFf__LATEST
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Firstly thanks for the valuable links.
I read them and understood the various concepts.
Now another customer approached us with a requirement to count humans outdoor and indoor in order to calculate crowd density and ensure social distancing. They have a big requirement as they are planing to deploy it across the city both outdoor and indoor without using cameras.
I think IWR1843BOOST EVM will be a good starting point for me to show them POC.
My only question is: Can IWR1843BOOST EVM be used for detecting, counting humans in an outdoor environment? One of the links given by you states - "mmWave Sensor to pinpoint location of objects in 100° field of view over a range of 5 m to 180 m". So, my understanding is that the sensor can be used to detect, locate humans in outdoor environments like city centre.
Please comment and give your opinion if my understanding is correct or not regarding using the sensor outdoor for detecting and counting humans.
