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...
