ELECTRONIC DEVICES FOR SECURITY ALARM SYSTEMS OF OBJECTS TERRITORY

Abstract

The estimation of influence of the microwave sensor frequency short-term instability on the information processing device operation accuracy in a security alarm system is presented. Results of theoretical calculation of microwave sensor noise characteristics and experimental data are given. Calculation of a sharply directed conic antenna with a dielectric lens is executed and results of experimental researches of its directional diagram in E - and H -planes are resulted.
