Abstract

The normal through-the-wall surveillance radar (TWSR) usually has one transmitting antenna (TA and one receiving antenna (RA), which is called monostatic TWSR. In this paper, a multi-static TWSR with one RA and many TAs is presented and this kind of TWSR works more efficiently than the normal one. FDTD method is used to numerically simulate the TWSR system and relative experiments have done. Besides, imaging process is carried out successfully on data of numerical simulation and imitating experiments of the multi-static TWSR by way of diffraction summation algorithm and frequency-wave number (f-k) algorithm.
