DETECTOR OF ECHO-SIGNALS OF MOVABLE TARGETS Russian patent published in 2008 - IPC G01S13/52 

FIELD: physics.

SUBSTANCE: invention is related to the field of radio engineering. Device contains serially connected band filter of signal, the first detector, the first low-pass filter and threshold unit, serially connected noise filter, the second detector and second low-pass filter, at that connected inputs of band filter of signal and noise filter and output of threshold unit are input and output of detector of echo-signals of movable targets. In order to achieve the specified technical result device is installed with summator and serially connected band filter of noise, the third detector, the third low-pass filter and unit of time delay. Input of band filter of noise is connected with input of detector of echo-signals of movable targets, the output of the second low-pass filter and output of time delay unit are connected via summator with the second input of threshold unit.

EFFECT: improvement of stabilisation of false alarms probability.
