即做不做差分处理我画出来的图差别很大,就是不做这个的话从Range_Dopper图上几乎看不到东西,但是做完差分再用进行连续的range_fft,doppler_fft画出来的图可以明显看到有点效果,我不知道这是不是正确的结果,因为您说应该不用预先做差分处理就能看出来。我把我采集到...
M3=fftshift(fft(M2',2*D)); %Second FFT for doppler information [My,Ny]=size(M3); doppler=linspace(-D,D,My); range=linspace(-N,N,Ny); figure;contour(range,doppler,abs(M3));grid on; xlabel('Range'); ylabel('Doppler') figure;mesh(range,doppler,abs(M3)); xlabel('Range'); ylab...

The data from an FMCW radar is 256x128, so I got 256 samples of every of the 128 ramps. There is only one target being scanned. Now I would just use fft(), calculate the magnitude and then find the index peak. But when I know where the peak is, which Im not too sure how to...

an FFT of the I/Q data, but that did not seem to work much better. Is there a soup to nuts example of how this MatLab function works that I might be able to process measured I/Q data properly to get a full Range Doppler Map output that...
Part Number:IWR1443BOOST 请问,如果计算的点云不需要速度信息,那么是否能够跳过doppler-fft这一步,在range-fft之后直接进行angle estimation?如果可以,那么angle estimation之前是否还要做doppler compensation? 如果不需要速度信息是可以省略doppler-fft的。 有一个类似的讨论贴,参考看一下: e2e.ti.com/.../2605281...
我们目前在使用PROCESSOR_SDK_RADAR_03_08_00_00中的cascade_radar_object_detect示例,使用的是AWR2243 MMWCAS-RF-EVM和配套的MMWCAS-DSP-EVM。 我们的目标是跳过doppler FFT,并且将numloops设置为1。我们注释掉了代码中的 doppler FFT 相关部分,并尝试修改numloops。我们发现,numloops是大于等于4的2的整数次幂时,...
关于热力图range heat map for zero Doppler数据来源的函数user6228350 Intellectual 380 points 求助,我想知道range heat map for zero Doppler数据是由哪个函数得到的,(类似这样的getAzimuthStaticHeatMap函数),我想知道在哪个DEMO里能看到,我查找了objectdetection.c,里面没有找到。
