Experiments on Through Wall Radar by Using an Ultra-Wide Band-FMCW Radar Trainer

A Through Wall Radar (TWR) is an important device for detecting the presence of targets hidden behind a wall, which is useful in a defense activity, or victims buried under soil or rubble after a disaster happens. In this paper, we present experiments of Ultra-Wide Band (UWB) Frequency Modulated Continuous Wave (FMCW) TWR using an FMCW Radar Trainer. The system operates in the frequency range of 2-3 GHz to achieve a desired range resolution, and which is obtained after processing beat signals and performs Fast Fourier Transform (FFT). The processing is performed in system modules that have been integrated with a microcontroller, which in turn is presented in a PPI (Plan Position Indicator). Experiments results show that a UWB-FMCW radar employed as a TWR can gives a good detecting and ranging performance.
