A family of "smart sensors" is described for implementation with very large scale integrated (VLSI) circuits and for use in information gathering, security and munitions fuzing systems. The sensors are based on a micro - signal processor technique capable of identifying, detecting, and/or classifying particular target signatures in real - time with a high degree of reliability and flexibility while meeting system constraints of low cost, small size, and very low power dissipation. A basic design is capable of accommodating multichannel inputs consisting of a variety of transducers. Specifically, applications are described using seismic and acoustic inputs. The algorithms used in these smart sensors are based on signal processing using spectral analysis. Microprocessor - based implementations, including analog conditioning, the micro itself, a special multiplier for more effective computations, and memory have been built and tested demonstrating the capability of a compact sensor system for intrusion and target recognition.
