Electronics Letters, Vol. 47(14), pp 824-8250013-5194http://digital-library.theiet.org/getabs/servlet/GetabsServlet?prog=normal&id=ELLEAK000047000014000824000001&idtype=cvips&gifs=yes&ref=nohttp://hdl.handle.net/10204/5487Copyright: 2011 Institution of Engineering and Technology (IET). This is a pre print version of the work. The definite version is published in Electronics Letters, Vol.47(14)The test and evaluation of modem radars using hardware in the loop simulators requires the use of wideband high-fidelity, digital radio frequency memories (DRFM) in order to generate realistic target retums. Important aspects of wideband DRFM design on a printed circuit board are highighted and the architecture of the DRFM that was implemented using commercial-off-the-shelf components is presented. The spurious free dynamic range of the DRFM was character ised as 47 dBc worst case over an instantaneous bandwidth of 800 MHz. An experimental pulse-Doppler radar was used to compare the fidelity of the returns from the DRFM and an optical delay line.enElectronicsRadar evaluationDigital radio frequency memoriesDRFMWideband DRFMRadar testArticleOlivier, K., Cilliers, J.
