As the existing technology is not ideal, saturation of radar receiver is inevitable. Receiver saturation will reconstruct the original echo signal and cause the target strength distortion and false targets. This paper established a nonlinear mathematical model of simplified saturation. The signal phase and amplitude errors are obtained by using quadrature demodulation. Then we analyzed the effects...
The paper designs and implements positioning monitoring system for vehicle based on GPS/DR (Global Positioning System/dead reckoning) technology. It solves the deficiency that vehicle can not locate and monitor when GPS signal loses, and improves positioning accuracy. The system uses S3C2410A microprocessor as the core of the entire system modules. The designation of the whole system, hardware and...
