Radar Cross Section Measurements of Frequency Selective Terahertz Retroreflectors
The radar cross section of spherical retroreflectors operating at terahertz frequencies is investigated. Several spherical retroreflectors with diameters ranging from 2 mm to 8 mm were fabricated and their radar cross section was measured at 100 GHz, 160 GHz, and 350 GHz. A frequency selective surface was applied to the retroreflectors to demonstrate proof of concept of narrow-band terahertz re...
متن کاملActive Calibration Target for Bistatic Radar Cross-Section Measurements
Either passive calibration targets are expensive and complex to manufacture or their bistatic RCS levels are significantly lower than the monostatic RCS levels of targets such as spheres, dihedraland trihedral corner reflectors. In this paper the performance of an active calibration target with relative high bistatic RCS values is illustrated as a reference target for bistatic RCS measurements....
متن کاملOn-Wafer Vector Network Analyzer Calibration and Measurements
The representative VNA block diagram (see Figure 1) shows the key elements of the analyzer. The RF source at the top provides the device-under-test (DUT) stimulus. A forward/reverse switch directs the RF energy to either DUT port. The test set uses directional couplers or bridges to pick off the forward and reverse waves traveling to and from each port, and down-converts these signals to four I...
متن کاملRadar Cross Section of Phased Array with Parallel Feed Network
The scattering characteristics of a phased array depends on its feed network. The variation of scattered fields within the feed network affects the antenna mode scattering. In this paper, an attempt is made to determine the radar cross section (RCS) of a planar array with parallel-feed network. The scattered field of the array is obtained by following the path of the signals through the antenna...
متن کاملVector-Network-Analyzer Calibrations
We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art WM-380 (WR 1.5) rectangular-waveguide vector-network-analyzer measurements over the frequency range 500–750 GHz. We use the analysis to assess thru-reflect-line, thru-short-match, and thru-short-radiating-open calibrations. The comparison shows that thru-short-match and thru-short-radi...
