Abstract:

The use of millimeter-wave radars allows a weight and size reduction of circuits and antennas, which is an important characteristic for Through-the-Wall Surveillance (TWS) applications. Furthermore, when using the millimeter-wave band, a large amount of bandwidth can be easily transmitted, given that the relative bandwidth is smaller. This leads to a high range resolution that allows for the discrimination of several targets that are very close in range, e.g., inside a room. The azimuth resolution is also improved due to the availability in this band of directive antennas with small dimensions. This paper studies the feasibility of using a millimeter-wave linear frequency-modulated continuous-wave radar in a TWS application. A TWS experiment in a real scenario has been done to demonstrate the validity of the theoretical analysis.

I. Introduction

This paper studies the feasibility of using a millimeter-wave linear frequency-modulated continuous-wave (LFMCW) radar in a Through-the-Wall Surveillance (TWS) application. Through-the-Wall Radar (TWR) is a challenge for surveillance in both civil and military applications [1]–[4]. Police and other law enforcement agencies are interested in the detection and localization of a person on the other side of a door, behind a wall, above the ceiling, or below the floor. This knowledge could provide a great advantage when making tactical decisions. Therefore, the study of techniques to compensate wall influences and to improve the performance of TWR has become an active topic in the last few years [5]–[11].
