Interferometry with the BladeRF 2.0 SDR

[David Lonard]

Hello everyone,

I recently purchased a BladeRF 2.0 SDR as a replacement for my older LimeSDR and XTRX SDRs. Here, I've attached a Python script that will do FX cross correlations with the BladeRF 2.0 (bladecorr1.py). Also included is a Gnuradio flowgraph that will allow you to visualize 122 MHz of bandwidth coupled with gr-fosphor.

The two attached jpgs show a FX cross correlated power spectrum and the cross correlation phase between two L-band patch antennas centered on the GPS L1 frequency at 1575 MHz.

So far, the AD9361 transceiver in the BladeRF 2.0 looks to be superior to that in the LimeSDR/XTRX.

See this website for instructions on how to install drivers for the BladeRF 2.0.

Unfortunately, I can't get 122 MHz sampling/bandwidth yet using the PySDR Python bindings. I hope that functionality will be coming soon.
