Abstract

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.

Description

technical field [0001] The invention relates to the field of active radiolocation and can be used in the design and development of digital broadband radar systems for river and sea navigation. Background technique [0002] Existing technologies include digital broadband marine radar proposed by Lowrance (www.lowrance.com), designed to closely observe space with high range resolution. [0003] Radar rangefinders are known (P.A. Bakulev / Radar Systems / / Textbook for Universities / / Moscow Radio. 2004, 320 p., III., p. 233-234). [0004] Known analog devices are classified as radar systems with continuous linear frequency modulation (LFM) transmission, in which both the formation of the transmitted signal and the processing of the received signal are done in digital form. The principle of operation of such radar systems is based on the use of continuous LFM detection signals and homodyne processing of signals reflected from objects located by the radar. Here, the transmission of ...
