摘要：

We introduce the application of high dynamic range (HDR) technique on radio frequency (RF) signals to increase the dynamic range of these signals beyond the hardware system limitations. To demonstrate this concept, this study uses commercially available software-defined radios (SDRs) with 48 dB of dynamic range. Two SDRs connected to the same antenna receive the same signal at differing gains. The results prove that the dynamic range does improve to 93.6 dB. Potential applications include radar systems, which typically require a high dynamic range.
