A RADAR STATION, FEATURING BROADBAND, LINEAR- FREQUENCY-MODULATED, CONTINUOUS-WAVE EMISSION

摘要

The invention relates to the area of active radiolocation and can be used in the design and development of digital broadband radar systems for river and marine navigation. The engineering task of this invention is aimed at simplifying the factory adjustment, thereby reducing the cost of the device in serial production. In addition, the engineering task also includes increasing the maximum permitted power of the emitted signal, which will not hinder the operation of the radar station due to overloading the receiver channel, as well as expanding the dynamic range of amplitudes of reflected signals, while retaining radar performance. The device contains a CPU with two ports, a display device, an angular position sensor, a master controller with five ports, a digital signal shaper, a timer signal generator, a beat signal processing unit, a correction filter, an m-channel radio signal adder, an m-channel radio signal splitter, mm transceiver modules containing a receiving and a transmission channel, and a two-channel signal splitter.
