I`m using X4M03 and want to do coherent integration to improve SNR. So I`d like to get more frame data per second. I refered to the link (https://www.xethru.com/community/th...-high-frame-rate-more-than-400.204/#post-1060) and adjusted the parameter pulseperstep to increase FPS. However, no matter how I adjusted the parameter pulseperstep, I couldn`t increase FPS more than 30 on my laptop computer. I tried same process on my desktop and find that the maximum FPS increased to about 50. 1. My question is, do I have some solutions to improve FPS? I used MATLAB API and XEP_X4_configure_radar.m to get frame data. Does using Python API or C API be effective to increase maximum FPS? 2. Also, are there any methods to improve SNR? I`m taking into account of using matched filtering, but don`t know how to produce reference signal. Thanks.
