Additional comments:

In this measurement A-DPIS method is used to cancel the high power direct path signal prior to the Analog-to-Digital Converter.

Measurement setup:

HR2 Rx hardware

HR2 Rx hardware

Dual channel coherent receiver built from RTL-SDR devices. The front module (ADPIS) is used to cancel the direct path interference prior to the analog-to-digital converter.

Measurement scenario

Measurement scenario

The antenna of the reference channel can be seen on the left side, while the surveillance antenna is on the right. The approachin target can be seen also.

Measurement scenario

Measurement scenario

The surveillance antenna is shown in the front.
