IWR1642: IWR1642 radar spec of FPS and detect point

Hi,

There is no blanket specification for maximum frame rate and/or number of detected points. The maximum FPS and the maximum number of detected points depend  upon factors such as Chirp design, software processing (Radar signal processing on the device), memory requirements and the data rate of the interface used for sending the data out (e.g. UART). For example: The SDK Out of Box Demo outputs information at 30 Frames per second.  

Factors such as Chirp design, processing and memory requirements are driven by application requirements such as maximum range, range resolution, maximum velocity, velocity resolution,  range and velocity accuracy, angular resolution and accuracy etc.

TI provides the mmWave Sensing Estimator tool which allows you to enter your application requirements (max range, velocity, resolution etc), including the required frame rate, and outputs the sensor configuration parameters and memory requirements. I would recommend you to enter the requirements in the Sensing estimator to perform a quick feasibility check against the selected device.

Please also look at the following threads which discuss these topics:

1. Linux/IWR1443BOOST: The upper and lower limits of MMW_MAX_OBJ_OUT.(Displayable range value.)

2. IWR1443BOOST: How to increase the number of point cloud data in 3D mode

Please mark this thread as answered if this resolves your query otherwise get back if you have more questions on this topic.
