Radar-Based Wireless Sensor Network for Distributed Measurement Systems

This paper presents a new topology of distributed measurement systems, which apply radar-based intelligent sensor network The nodes of distributed measurement system use an alternative current loop circuit as a signal conditioner of the sensor system. The optimal procedure for model parameter estimation based on the maximum likelihood method is described. The convenient calibration technique of the sensor system that enables to simplify the necessary calculations drastically is offered. Description of radar communication channel of improved noise immunity is given. The idea of channel implementation bases on information signal coding-decoding stating on the special code signal feature. The coding-decoding procedures are describes and discussed.
