Linear frequency modulated continuous wave (LFMCW) radar has been applied to the field about short‐range target detection. In this article, in order to achieve the low cost and general short‐range target detection, a semi‐physical LFMCW radar system is designed to estimate the distance and speed of the moving target in real scenarios. Meanwhile, the received echo signal is processed by using sparse Fourier transform and fast Fourier transform so as to further improve computational efficiency. Experimental results confirm the effectiveness of the designed semi‐physical LFMCW radar system. More importantly, the designed system also lays the foundation for the future engineering application for the LFMCW radar.
