DEVICE WHICH LOCATES RADIO EMITTER Russian patent published in 1997 - IPC

FIELD: radio engineering, in particular, radars. SUBSTANCE: device has network of radio engineering stations which measure emitter signal characteristics. Outputs of said stations are connected to corresponding inputs of signal processing unit. Ranging coordinates calculation unit, unit with data for structure of road network and road lines approximation unit are introduced to accomplish the goal of invention. Output of signal processing unit is connected to first input of ranging coordinate calculation unit which second input is connected to output of road lines approximation unit. First output of ranging coordinate calculation unit serves as device output, its second output is connected to input of unit with data for structure of road network. Output of latter unit is connected to input of road lines approximation unit. Roads are used as additional position lines. EFFECT: increased precision of detection of emitter in conditions of non-uniformity of trace characteristics. 4 cl, 5 dwg , 1 tbl
