Abstract (in Japanese) (See Japanese page) 
(in English) Communication-radar integrated systems that perform wireless communication and radar sensing at the same time with common radio resource have been studied. Communication-radar integrated system using OFDM with mismatched filter (MMF) radar detection achieves superior multi-target separation performance because sidelobe level of the range pulse is lower than that of correlation-based detection. However, a large Doppler shift caused by movements of transmitters or objects degrades the sidelobe performance. In this paper, simulations are conducted to identify the Doppler shift effect on the performance. Moreover, we propose an MMF output averaging method to improve sidelobe characteristics and multi-target separation performance. The simulation results show that the sidelobe levels are reduced by up to 10 dB with the averaging method. It is also shown that the multi-target separation performance is further improved by the proposed method.
