Interrupted Transmitting and Receiving Parameters Design and Echo Reconstruction Method of Pulse Signal in Anechoic Chamber

With the development of Hardware-in-the-Loop simulation, infield experiment as an important measurement method of target characteristics has been widely concerned by researchers. Due to the limited space of anechoic chamber, the transmitted and echoes are coupled at the receiver. To handle this problem, the interrupted transmitting and receiving (ITR) experiment system is constructed in this paper by combining the intermittent sampling principle and relative time delay of echo. Furthermore, the strategies of ITR parameter optimization and target echo measurement results are discussed. Experiments show that the system can accurately extract the scattering characteristics of space target echo. Based on the target probing results, the effectiveness of ITR echo reconstruction method is verified.
