Micro-electro-mechanical system (MEMS) technology offers sensors with lower cost, smaller size, and lower power consumption. In this paper, a kind of low cost motion-sensing system based on MEMS sensors is developed. The objective of the design is: small volume, light weight and low cost, in order to be used in many fields. The constituting principle of the system is described and the algorithms and...
Because vehicles moving over ground generate a succession of impacts, the soil disturbances propagate away from the source as seismic waves. Thus, in the battlefield environment, we can detect moving ground vehicles by means of measuring seismic signals using a seismic velocity transducer, and automatically classify and recognize them by advance signal processing method. Because seismic sensor is...
