STEMlab from Red Pitaya at the Heart of Radar Warning and Information Disaster Management System

Pitaya, the company that is pioneering the move to low cost,
open-source, reconfigurable instrumentation with its credit-card-sized
STEMlab™ platform, today announced that a consortium including members
from a major European research organisation, two German universities and
industry, is using STEMlab to perform waveform synthesis, IF signal
sampling & signal processing on a new radar warning and information
system for applications in disaster management (RAWIS) that is currently
being developed.

During a search and rescue operation, emergency teams and trapped
survivors are exposed to high risk from partially- destroyed buildings
and structures which can collapse causing injury. More, the situation is
constantly changing as debris is moved. RAWIS will monitor any movement
in the disaster environment and warn individuals of any danger. Harmless
motion – people, rescue vehicles, animals, tree leaves etc – must be
successfully suppressed. The RAWIS system consists of a main radar
system which monitors the entire scene and measures submillimeter debris
movements of any debris, auxiliary radars to perform measurements of
individual hot spots, and units which are fastened to clothing worn by
the rescuers.

Auxiliary radars, which can cover hidden or covered areas, operate
within the V-Band as the best compromise between resolution, size and
system cost. Synthesis of the Tx waveform, sampling of the IF signal and
signal processing are performed using Red Pitaya’s STEMlab, a low cost,
credit-card sized FPGA board suitable for Software-defined Radar (SDR)
applications. This platform contains dual-channel AD/DA conversion
capabilities with 14-bit resolution at 125MHz sample frequency.

Comments CEO Rok Mesar: “This is a perfect example of industry and
academia working together to solve a complex challenge. The high
performance, small size, low weight and low cost of our STEMlab platform
will enable this system to be easily and cost-effectively deployed,
ensuring that rescue teams are kept as safe as possible.”
