Indoor measurements were performed to examine the feasibility of using range-Doppler processing for human motion detection in a highly cluttered environment by the multistatic ultra-wideband (UWB) radar. A novel hypothesis-testing based range migration compensation algorithm, which is especially suited to UWB radars, is proposed to increase the coherent processing interval for range-Doppler processing. For each receiver, the multistatic UWB radar provides a video sequence constructed by high-resolution range-Doppler images of a human target, which is promising for the analysis of human target characteristics.

This research proposes a scheme of field programmable gate array (FPGA) to generate an impulse-radio ultra-wideband (IR-UWB) pulse. The FPGA scheme consists of three parts: digital clock manager, four-delay-paths stratagem, and edge combiner. The IR-UWB radar system is designed to detect human subjects from their respiration underneath the rubble in the aftermath of an earthquake and to locate the human subjects based on range estimation. The proposed IR-UWB radar system is experimented with human subjects lying underneath layers of stacked clay bricks in supine and prone position. The results reveal that the IR-UWB radar system achieves a pulse duration of 540 ps with a bandwidth of 2.073 GHz (fractional bandwidth of 1.797). In addition, the IR-UWB technology can detect human subjects underneath the rubble from respiration and identify the location of human subjects by range estimation. The novelty of this research lies in the use of the FPGA scheme to achieve an IR-UWB pulse with a 2.073 GHz (117 MHz–2.19 GHz) bandwidth, thereby rendering the technology suitable for a wide range of applications, in addition to through-obstacle detection.

“…Through the wall (TTW) detection has received significant attention in recent years as a result of the wide potential applications. Most TTW systems involve some form of active UWB radars [11][12][13]. An X-band microwave signal based through-wall detection device is claimed by GTRI in [14] called Radar Flashlight for the purpose of sensing the small body motion by taking advantage of the high frequency RF signal.…”

In this paper, a reconfigurable real time passive wireless detection system is described. The system is based on a Software Defined Radio (SDR) architecture. The signal processing method and processing flow that enable through wall target detection are introduced. The high-speed noise and interference mitigation methods implemented in the system for through wall target detection are also described. A series of experimental results are presented for both large and small human body movements in through wall scenarios. It is shown that the high resolution Doppler event history implemented in the system enables the system to recognize and distinguish between a range of body movements. The results demonstrate that this real time SDR based wireless detection system is a low cost solution for human movement and recognition with a wide range of applications.
