Abstract

The invention discloses a ship navigation radar system and a ship navigation method, which solve the problem of unfavorable navigation effect of a radar in the prior art. The ship navigation radar system comprises an analog-to-digital conversion module, a coordinate transformation module and a superposition output module, wherein the analog-to-digital conversion module is used for converting an analog-quantity video signal collected by a radar into a digital-quantity radar image signal; the coordinate transformation module is used for carrying out the coordinate transformation of the digital-quantity radar image signal to obtain a signal of a radar image in a plane rectangular coordinate system; and the superposition output module is used for superposing and outputting the signal of the radar image in the plane rectangular coordinate system and information of an electronic chart.

Description

technical field [0001] The present invention relates to marine radar technology, in particular to a marine navigation radar system and a marine navigation method. Background technique [0002] The overall technical level of my country's marine navigation radar is low, and its independent research and development capabilities are weak. For a long time, due to the serious insufficient and discontinuous investment in scientific research and development, technology introduction and technological transformation of the government and enterprises in the field of marine navigation radar equipment, most enterprises have not digested, absorbed and re-innovated the technology introduced in the early stage of reform and opening up, or have not carried out tracking technology. The overall technical level of my country's marine navigation radar equipment products is far behind the international advanced level due to many reasons such as the introduction, production enterprises have not bec...
