usually the algorithm is based on phase difference, MUSIC or ESPRIT. There is a software package called gr-doa can be found on github, but it uses the ettus research X310 which is quite expensive. There is no ready to use software based on hackrf yet.
I’m a beginner myself, learned some algorithms at school, but have never achieved on real world hardware yet. These days I will try to use a 2-channel limesdr to visually see what difference in phase will I detect while the angle of arrival changes, then I will write the software to automatically convert that to angle. > 在 2017年2月16日，下午4:35，Rustu Yucel <rustuyu...@gmail.com> 写道： > > I guess possible but dont know which software can help to achieve this? > Particularly setting up everything in working order in a challenge for me. > Any help welcomed :) > > On Thu, Feb 16, 2017 at 11:02 AM, shaozhuyuan <13671890...@139.com > <mailto:13671890...@139.com>> wrote: > I saw someone used 3 synchronized rtlsdr as passive radar.
