Concealed weapons detection system |
摘要 |
A weapons detector (12) and method utilizing radar. The system comprises a transmitter (27) for producing an output (14) of frequencies of a set of self-resonant frequencies of weaponry; an antenna (28) directing the transmitter output toward locations potentially having weaponry and collecting backscattered signals (15); a receiver (29) receiving the backscattered signals(15) and operating over a range of the self-resonant frequencies; and a signal processor (30) for detecting the presence of a plurality of the self-resonant frequencies in the backscattered signals (15). Accuracies of greater than 98% can be obtained at distances, preferably between 4-15 yards. The weapons detector (12) is capable of detecting metal and non-metal weapons (16) on a human body (13) in purses, briefcases and under clothing; and discerning weapons (16) from objects such as belt buckles, coins, keys, calculators, cellular phones.
