Embodiment Construction

[0016] Referring now to Figure 1, a block diagram depicts the device of the present invention. The device preferably includes a transmitter 11, an antenna 12 for transmitting UWB pulses, an antenna 13 for receiving return signals, a signal processing device 14 for analyzing these return signals, and a data processing device for processing the signal data. 15 and a display 16 for displaying these results. The pulses from the antenna 12 detect the object 17 of interest, and these return signals are reflected on the antenna 13.

[0017] There is a transmitter 11 in the prototype version of the system, which includes a 2×2 solid-state broadband antenna array 12. A radiation pulse is emitted from the antenna array 12, the rise time of the pulse is approximately 100-500 picoseconds, and its fall time is approximately 5-10 nanoseconds. The antenna array 12 generates an electric field near the transmitter 11 on the order of 5-7 kV / m. A dc (direct current) battery supplies power to the...

Abstract

A method and system are disclosed for detecting objects of interest in a target area using ultra wide band (UWB) RF signals. A transmitter and antenna array generate ultra wide band RF impulsive signals that are used to probe a target area that may include an object of interest. An antenna and a signal processor receive return signals from the target area and process the return signal to generatea set of coordinates. The coordinates of the processed return signals are compared to coordinates of known objects in a pre-existing database to determine whether there is a match between the return signal and a known object. When there is an indication of a match, the existence of the known object is displayed to an operator of the system.

Description

Technical field [0001] The present invention relates to a device and method for detecting objects using time-domain pulse signals, and more particularly to a device and method for detecting objects that are visually obstructed using ultra-wideband (UWB) RF signals. Background technique [0002] UWB technology has been around for decades and has been used in radar-based applications in the past. The development of high-speed switching technology makes UWB technology more attractive for low-cost user communication applications. Many companies are now working on R&D plans that are studying the extension of UWB technology to high-speed communications, and the FCC is setting emission limits, which will allow UWB communications systems to be used on an unauthorized basis. [0003] UWB radio equipment is an RF communication device that uses high-bandwidth microwave pulses to transmit digital data with very low power density on a wide frequency spectrum. These devices can transmit data a...
