Book excerpt: This report discusses various Concealed Weapon Detection (CWD) efforts and technologies which have evolved over the past few years. Information provided in this final technical report summarized programs being pursued based on National Institute of Justice (NIJ) and DARPA Grants and contract awards to move toward safe and dependable sensors to address the concealed weapon problem. These weapons are a major threat to both military and law enforcement personnel. The capability for CWD is a critical operational need for the Military, Federal, State, and Local Law Enforcement communities in their various areas of operations, unique environments, and regulations each must operate under. The CWD technological challenge of the 1990's, and beyond, will include the detection of metallic and non-metallic weapons. Detection of concealed weapons posses severe technical challenges based on the target phenomenology, background and obscuring medium. Based on the maturity of the technologies and proprietary information restrictions, detailed information was not available to support our investigations and additional work will be required in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Existing weapon detection systems such as metal detectors and X-ray baggage scanners have many drawbacks. While metal detectors can only detect metallic objects, X-ray scanners are unsafe for use on passengers. Also, these systems can only scan people within a short range. These limitations of detecting potentially harmful objects have led to tragic events such as the 9/11 attack on the world trade centre and the 2008 terrorist attack in Mumbai. Development of more advanced security systems would help in curbing such terrorist attacks. These systems could also be used to help security officials in tackling knife and gun related crimes in the streets. The aim of this research is to develop a concealed weapon detection system using acoustic waves. Ideally, the system would have large standoff distance, should be cost-effective and easy to manufacture and would be able to detect both metal and non-metallic weapons. Different techniques such as acoustic signature, resonance acoustic spectroscopy and acoustic imaging were analysed. Acoustic signature techniques identify the target by comparing the acoustic waves reflected by the target to a database of previously recorded acoustic reflections. Resonance acoustic spectroscopy was used on the data acquired using both experimental measurements and Finite Element simulations. A series of resonant frequencies from the acoustic waves reflected by the concealed target were extracted using this technique. This series of resonant frequencies that are unique to the target were used to identify the target. Acoustic camera was used to experimentally record the acoustic reflection from different targets. This was then used to develop images of concealed targets. These tests were performed using commercially available array speaker systems. The probability of improving these results using a better designed ultrasonic or acoustic array speaker system was analysed. This was done by changing different array design parameters and obtaining a highly focused acoustic beam. The results from the experimental tests and Finite Element simulations proved the possibility of using acoustic waves for concealed weapon detection. In the acoustic signature measurements, the frequency spectra of the reflected acoustic waves were shown to be different for different targets. The results from resonance acoustic spectroscopy showed structural resonant frequencies in the frequency spectra that corresponded to the natural frequency of the target. Using acoustic camera kit the image of the concealed target was identified. The array results showed the formation of focused beams for different array configurations. The results showed the formation of grating lobes and side lobes when the inter-element gap became larger than the wavelength of sound waves at the excitation frequency. Finally, a program using neural network was developed to demonstrate how the natural frequencies from the target could be used to identify them. This research work provides a proof of concept of different acoustic wave-based detection and imaging techniques. It has shown the possibility of detecting concealed targets at standoff distances. Using parametric arrays highly focused acoustic or ultrasonic beams could be generated which could be focused on a person suspected of carrying a weapon in a crowded environment. The sound waves reflected back could be analysed using the resonance acoustic spectroscopic technique or one could use the acoustic camera to generate images of targets in real-time. The use of acoustic waves would also help in keeping the cost and complexity of the equipment to a minimum. It also ensures that the public is not exposed to any harmful radiation. The techniques described in this thesis would significantly support the development of a commercially viable, robust acoustic waves based concealed weapon detection system.

Book excerpt: The major findings of this effort clearly demonstrate that Non-linear Acoustics is a low cost alternative to conventional imaging methods for concealed weapons detection. Our approach is to use ultrasonics to create a localized zone where non-linear interactions generate a lower frequency acoustic wave that is steerable and is able to penetrate clothing better than direct ultrasonics. We have been able to detect guns of various sizes, box cutters, knives and distinguish weapons from non-weapons including plastic devices. Sophisticated software generated signals with customized transducer/receiver design have been able to provide characteristic information about a hidden weapon 15 feet away and classify the weapon based on a database approach. Most recently improved software allows user- friendly display of results with images. We are confident of the readiness of our work for prototype development. In addition to being able to detect the weapons mentioned above, we have also been highly successful in imaging improvised weapons (received from the DOJ/AFRL lab) from a near range distance.
