Intelligent Trajectory Monitoring Receiver

Trajectory supervising receiver is a special device , used for supervising status of fuze in the shooting range or library . We can improve the efficiency of experimentation and decrease expenditure greatly by using the device . And the focus of my treatise is how to capture the signials accurately and quickly from the complicated electromagnetic background .Recuring to the assistance from ADS , which is used for radio frequency simulating ,and general circuit simulating software - MULTISUM , several key technoledgeincluding RF signal's disposing , local swept oscilating circuit , system control and frequency display etc. were discussed emphatically in the treatise . Not only the relevant theory but also the hardware circuit design were elaborated explicitly . And the main contents are as followings .(1) According to the theory of microstrip line , a bandpass filter from 3.4GHz ~ 3.8GHz was designed with the shape of Parallel-Couple microstrip line by the aid of ADS.(2) Exerting the phase-locked frequency synthesize thought and voltage-controlled oscilation principle , a local swept oscilating circuit unit from 1.58GHz ~ 1.78GHz was designed . At the same time , Recuring to the programed phase discriminator and frequency divider , the value of work frequency was scaled with digit accurately .(3) The trajectory supervising receiver was intelligentized with the heart of microprocessor and E2PROM for outer memory storage . according to the application software , the receiver can discriminate the real signal and the jamming signal. It can also display the value of captured signals .
