IWR1443BOOST: IWR1443BOOST and IWR1642BOOST questions

Hi Mickey,

1. Both devices (IWR1443 and IWR1642) are capable of natively detecting 160 kmph, but depending upon the range requirements, IWR1642 may be a better candidate due to it's larger Radar cube memory. The reason is that with higher velocity, you need to chirp faster (more often) to meet the SNR needed for the same detection range and hence need more memory to store the resulting radar data. Also, you should consider other system requirements in mind i.e. Max range, Range resolution, Max velocity (160 kmph), velocity resolution etc. The best way to do so is to enter the required scene parameters (i.e. range, velocity etc) in the mmWaveSensing Estimator and evaluate which device best meets the desired criterion. For your reference, I have attached a snapshot which shows one possible configuration with IWR1642 for 160 kmph velocity.

2. IWR1443 and IWR1642 EVMs do not support connecting an external patch antenna.

3. I'm not sure I understood this question. Can you please provide more details?

Thanks

Hi Mickey,

Thanks for the info. The EVM along-with the Out of Box Demo is capable of detecting objects and measure their distance, velocity and angle of arrival as well. Besides distance, velocity and other factors, the detect-ability of the object depends upon it's RCS which is a measure of how well the object reflects Radar waves in the direction of the antenna. As I indicated in my previous response, the best way to start is to list down your sensing requirements i.e. Maximum range, Maximum  velocity, RCS (depends upon the type of object), etc and enter them in the mmWave Sensing Estimator to quickly get an idea of what you can achieve with each device (IWR1443 or IWR1642).

From a software perspective, the mmWave SDK provides the basic processing chain to configure the sensor for a given set of parameters and perform the operations needed to measure distance, velocity and angle on both IWR1443 and IWR1642. The mmWave Out of Box examples provide sample implementation of the basic processing chain so please look at those as well. We also have a the Traffic Monitoring Object Detection and Tracking Reference Design Using mmWave Radar Sensor which provides a sample implementation of clustering and tracking algorithms for a traffic Monitoring application and provides the source code as well.
