MUNIN 1005-IF

MUNIN was specifically developed for ELINT & CommsES applications connecting one or more analog receivers to the configurable IF inputs. The real-time spectrum monitor is ideal for capturing & recording new and unknown emitters. The combination of the standard API with the large circular buffer ensures lossless recording when controlled by your own operative environment.

BENEFITS

  • Gapless & lossless IQ data recording ensuring maximum results for offline analysis
  • Superior global timing precision enabling TDOA measurements
  • Modular COTS platform allowing configuration and adaptation to mission specific requirements

Gapless & lossless IQ data recording ensuring maximum results for offline analysis

The main purpose of this wideband signal recorder is to capture all IQ data of any emitter of interest enabling complete offline analysis including identification and classification.
MUNIN is specifically designed with this purpose in mind why great development effort was put into designing a solid streaming engine capturing all IQ samples for hours or even days. The streaming engine takes care of latencies introduced by manual operations or by third-party processing software, thus ensuring lossless recording of newly identified emitters.


Superior global timing precision enabling TDOA measurements

Performing TDOA measurements with distributed recording systems requires superior global timing precision.
MUNIN provides proven timing precision better than 10µs relative to coordinated universal time (UTC) enabling geolocation of RF emitters based on TDOA technique.


Modular COTS platform allowing repurposing to mission specific requirements

MUNIN can be configured with a combination of wideband & narrowband IF inputs and optional IF output. The IF input center frequencies and real-time bandwidth can be adapted to various analog receivers. Storage configurations range from 8TB to multiple hundreds of TB storage capacity. All in all, it allows to quickly reconfigure and reuse existing equipment by changing the software or making hardware upgrades to the MUNIN recorder.

FEATURES

 

Gapless recording. MUNIN records all IQ samples continuously without gaps maximizing post-processing results.

Long recording time. MUNIN offers standard RAID configurations from 8TB to 192TB with industrial grade SSD disks. Dependent on the channel configuration you can continuously record data from hours to days. The storage capacity can be expanded beyond 192TB and adapted to mission specific requirements.

Pre-trigger buffer. MUNIN comes with a circular buffer capturing pre-trigger events. The buffer captures pre-trigger events from a few seconds to minutes. It also acts as a circular buffer during streaming to disc operation ensuring lossless recording.

Server client architecture The server client architecture separates all time critical tasks from the non-time critical tasks. It allows parallel remote operation from several clients, whether the client is manually operated or controlled by any third-part signal surveillance or processing software. With UDP multicast it is the operator’s freedom to listen to any signals of interest.

Data & file format. The data is saved as Midas platinum (BLUE 2.0) file format. It can also be saved as binary file in the open file format TDMS, which is optimized for streaming applications. Both file formats can be opened by third-party software like MATLAB® for analysis.
Channel data and radio spectrum packets are streamed in a proprietary format. It is possible to configure the order of IQ samples and to choose between little-endian and big-endian. Other data packet formats like VITA 49 can be provided on request.

Timestamping. To enable TDOA measurements with distributed systems MUNIN can be synchronized with the built-in GPS / IRIG-B receiver. For improved timestamp accuracy below millisecond resolution, the recorder uses a PPS (Pulse Per Second) signal. The timing information is distributed via NTP (Network Time Protocol) to all modules.
