| Popis: |
Standard hardware techniques for the linearization of the frequency sweep in FMCW radars are difficult to implement and often offer only moderate improvement in linearity. A simple software-based linearization technique is introduced for short-range FMCW radars, and compared with a simple hardware linearization scheme. These techniques have been verified in an existing C-band FMCW scatterometer, and result in a dramatic focusing of the point return. The resulting range resolution (measured) approaches the theoretical limit, with a >20 dB reduction in sidelobes. |
