Abstract:

Methods of realizing the load impedance required for radar cross section control of conducting bodies are discussed. It is shown that passive loading, using frequency-dependent dielectricmagnetic materials in a radial or coaxial line, requires a frequency dependence which is not exhibited by any known material. A number of active synthesis approaches are examined, with emphasis on those using the Negative Impedance Converter NIC. Experimental results are given for a particular NIC realization operating in the 5 - 10 MHz range the circuit is shown to be capable of producing the load impedance required for a cross-section reduction of 13dB or more over a 21 bandwidth.
