AWR1642BOOST: Small animal intrusion detection application

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Hi,

I am part of a team that is looking for a radar device that can detect and record small animal intrusions (mainly raccoons and squirrels) in a 5 acre square lot. We have the AWR1642BOOST EVM and have done some testing with the out of box demo. We are not sure if this device can provide the optimal range and resolution we need.

Before we go any further with this project, we would like to know if it is possible for this device to modified to meet our needs. We have thought about putting these devices along the perimeter of the lot along the fence lines, or possibly in the center of the lot with multiple devices arranged for a 360 degree field of view.

Any feedback would be greatly appreciated.

Thanks.

    Jeff,

    We definitely appreciate your interest in our mmWave sensors! The AWR1642 is going to be well suited for your application since it will work very well up to 100 meters with resolution between two objects on the order of centimeters. Furthermore, the integrated DSP in the AWR1642 is going to be able to help your application not only detect animals but also differentiate these animals from humans or other objects.

    It is very possible to modify the device by working with the particular chirp configuration. Keep in mind that the out of box demo is just that, it is a ready to use application designed for detecting objects at your workstation. Through some simple modifications you can tailor the device for a much larger and dynamic scene.

    Let me know if you have more questions.

    Cheers,
    Akash

    Hi Akash,

    If the detection range is 100m in a sunny day, what is the detection range in a rainy day ? Do you have any test data about rain fading ? Thanks.

    Hi Martin,

    Although we don't have any explicit test data, mmWave Sensors can detect the same distance on a rainy day. If you'd like to discuss this more then feel free to open up a new thread!

    Akash:

    Can you give me some directions on how to modify the software to tailor the device for the largest scene possible with 100m range? I am relatively new to using the SDK's and radar so I am not too familiar with how to work with the chirp configuration.

    Also, is there a particular value associated with a return signal that we can use to determine the difference between an animal vs. human? I want to record detection data and write to a file for post processing. For example, I'm thinking in terms of some value like 2.2 corresponding to a squirrel or racoon and 5.5 corresponding to a human. I know those are just arbitrary numbers but my goal is to work with the recorded data to discern between these objects.

    Thanks

    Jeff,

    You are going to want to take a look at SNR of the return signal for identification of particular animals. A large animal will tend to be easier to detect and thus have a larger SNR.

    If you are still interested in working the SDK then I'd highly highly recommend spending some time going through the mmWave Training series. Many of your questions plus more will be answered here: training.ti.com/mmwave-training-series
