1.1 This test method permits the rapid measurement of apparent relative permittivity and loss tangent (dissipation factor) of metal-clad polymer-based circuit substrates in the X-band (8 to 12.4 GHz).

1.2 This test method is suitable for testing PTFE (polytetrafluorethylene) impregnated gl...

1.1 This test method covers the nondestructive determination of thickness of bound pavement layers using short-pulse radar.

1.2 The accuracy and applicability of this test method is a function of these components: radar-system penetration, radar-system resolution, and the dielectric const...

Three forecasting models are set up: the auto-regressive moving average model, the grey forecasting model for the rate of qualified products Pt, and the grey forecasting model for time intervals of the quality catastrophes. Then a combined forewarning system for the quality of products is establishe...

The influence of pulse repetition frequency(PRF) on performance of wireless digital timeuhopping spread spectrum(THSS) ultrawide bandwidth(UWB) radio systems with PPM in dense multipath fading environments is firstly investigated. The receiver used in this UWB system is a hybrid selection/maximal-ra...
