RADAR SYSTEM Russian patent published in 2016 - IPC G01S13/58 

FIELD: radar.

SUBSTANCE: invention relates to radar and can be used in security systems for detection and measurement in real time of trajectory parameters of moving objects during control over large areas of territories, water bodies and air space.

EFFECT: technical result is creation of a digital radar system with a wider sector of observation (up to 360 degrees) due to presence of multiple radar modules with a set of transceiving antennae, located in different planes; with high degree of protection against external active interference due to that each of radar system modules is configured to encode initial phase of each probing pulse according to a random law to generate a unique phase key for coherent pulse sequence, which is used for subsequent matched filtering of "own" echo-signals with random phase compensation, wherein echo signals from neighbouring "foreign" radar systems, as well as external harmonic (quasi-harmonic) active interference are subjected to destruction in digital receiving channel of radar module as a result of their phase modulation; with increased range of detection owing to compensation for attenuation of echo signals in switch, which is part of radar module.
