StingRay: Gated-CW Radar Architecture - 2

The StingRay Gated-CW RCS measurement system, developed to work in conjunction with the Agilent Technologies Performance Network Analyzer (PNA), offers significant improvements in RCS measurement speed and sensitivity. The system provides performance enhancements beyond other VNA based Gated-CW radars while providing a lower cost alternative to pulsed IF radar implementation. # Key features • Base sensitivity improvements: 10-20dB over previous systems • Accuracy: efficient packaging means additional performance gains • High speed data acquisition; Increased measurement speed: 10 x faster...

System overview Quasi-monostatic Radar Antenna Configuration FR81058 Pulse Modulator 2-18 GHz TX Gate Ref In Ref Out Test Out Pulse Modulator Timing Unit Agilent 81150A Color Printer AL 48062 Positioner Controller PNA Series Vector Network Analyzer Test In Ref In Ref Out Efﬁcient packaging means performance gains and more accuracy Improvement (between 10-20 dB) is derived by using a power ampliﬁer inside the pulse modulator which adds to the sensitivity of the PNA. It is preceded by a low noise ampliﬁer on the receive side. The use of high isolation antennas, in conjunction with the pulse...

StingRay: Gated-CW Radar Architecture - 4

SPEED High speed data acquisition > Speed/sensitivity trade-off readily optimized Data acquisition speed is greatly increased over that previously available by taking advantage of the order of magnitude improvement in frequency switching speed offered by the PNA synthesizer as well as the improvement in sampling speed. The wide range of IF bandwidth choices available in the PNA adds to this capability. > Several methods to rapidly attain access to data - Export to: ASCII, Microsoft Excel, MATLAB, or Mathematica - Access binary data ﬁles directly through a File System API and a File System...
