Target probing based on wideband pulse radar is a challenging task for radio frequency simulation (RFS) in anechoic chamber. Due to the long time duration of pulse radar signal and the limited space of anechoic chamber, the reflected signal returns before the pulse radar signal is fully transmitted, which makes it difficult for the signal reception. As a consequence, the target high-resolution range profile (HRRP) cannot be obtained for target imaging and recognition. In this paper, we propose a novel strategy that contains two steps to solve this problem and obtain the target HRRP. First, the randomly interrupted transmitting and receiving (R-ITR) method is proposed to receive the pulse radar signal in RFS. Second, the target HRRP is reconstructed by compressive sensing (CS) since the R-ITR echo is piecewise sparse. The protocol to choose R-ITR parameters and performance of HRRP reconstruction are provided. Simulations and experiments with different R-ITR parameters are also conducted to verify the effectiveness of the proposed method.
