- Abstract
- Dc-offset estimation of quadrature continuous-wave (CW) radar has been studied for years. Studies have shown that the estimation error increases when target movement with respect to the radar is small. This paper presents a method that uses multiple simultaneous CW frequencies for the dc-offset estimation, which makes the dc-offset estimation easy in contrast to the conventional quadrature CW radar. A dc-offset estimation method using the multiple CW frequencies is presented to demonstrate that the multiple CW frequencies provide sufficient information for the dc-offset estimation.
