Passive radar direction finding aerial objects DEVICE

摘要

Passive radar device DF air objects.; The invention relates to radar devices and can be used in surveillance radar producing measurement angular coordinates emitting air objects.; The object of the utility model is to enable the correct display of the results of direction finding radiation sources with different frequencies and different angular coordinates measured in the plane of the bearing.; This object is achieved by the fact that in the known prior art device by complementing its filter assembly and the indicator it is possible to correctly display the results of passive DF multiple radiation sources at different frequencies and at different angular coordinates. In this case the input of the filter is connected to the output of the amplifier of the intermediate frequency sum signal, and every s-th output of the filter unit of the S outputs, where S - the number of narrowband filters, defined as the analyzed frequency band the ratio ΔF _en to a single narrow filter bandwidth Δf _f associated with the corresponding s-th second indicator input, the first input of which is connected to the output of the divider.
