Modeling & Simulation

Our arraying technology coupled with specialized algorithms enables precision angle-of-arrival determination.  This process also produces AOA error metrics with each AOA.  AOA propagation can be extended to emitter GEO-location.  Using AOA methods, the signal direction can be precisely determined.  Using specialized hardware, dense signal environments can be characterized.

BSS key features
Angle of arrival and geo-location determination

In this example, three signals with overlapping frequencies and bandwidths were detected and separated using Blind Signal Sorting (BSS) methods.  The ‘green’ signal was found in channels 3-6 above as indicated by the high correlation scores (~1) in the red box.

Cross-sensor data processing

We have decades of experience in multi-sensor data and image fusion.  'Hidden' information can be derived using specialized arrays and various sensor technologies.  Some capabilities include:  3D data (LIDAR) alignment, fusion, and visualization; atmospheric correction of imagery;  video object tracking;  image registration;  image fusion.   Specialized Arrays recently proposed a novel LIDAR, video, and sonar system for the reduction of by-catch during trawling. 

We also offer detection, sorting, and characterization of co-channel short duration emitters (RADAR).  In these environments, our Blind Signal Sorting (BSS) and Angle-of-Arrival (AOA) techniques can detect, sort, characterize, and locate more emitters than degrees of freedom.

Blind Signal Sorting (BSS)
  • No a priori information and no calibration is needed

  • Handles dispersive environments

  • Mission specific BSS methods

  • Precursor to adaptively forming Beams and Nulls (Interference nulling)

  • Capable of very deep nulls in narrow bandwidths

  • Handles a wide dynamic range, input power, bandwidth, emitter modulations, waveforms

  • Multiple simultaneous co-channel emitter separation

  • Specialized channelized hardware 

  • Enables number of sorted emitters to be greater than DOF

  • Capable of identifying:  Number of emitters, emitter steering vectors, polarizations, powers, bandwidths, locations

  • Integrated cross-ambiguity methods

Signal environment characterization

Specialized Arrays principals have decades of experience in multi-signal recovery and characterization; both analog and digital methods.  Of particular interest are dense signal environment where the signal of interest is weak and dominated by co-channel interference.
