Problems solved by technology

Therefore, the performance adjustment of the current marine radar can only consider the overall general requirements, or can only consider the observation requirements of some targets, so the detection performance of the radar has not been brought into full play

Abstract

The invention discloses a marine radar detection system and a detection method thereof. The system comprises a radar antenna, a radar receiver, a radar transmitter and an ARPA (Advanced Research Projects Agency) radar terminal. The radar transmitter receives a control instruction and outputs state detection data; the radar receiver receives the control instruction and outputs the state detection data; and the ARPA radar terminal is provided with self-adaptive detection processing and control software and transmits a working state setting instruction to a filter for single detection and target track processing in the radar transmitter, the radar receiver and the ARPA radar terminal. The method comprises the steps of land and shoreline detection, echo character parameter calculation, the detection and tracking interaction of a correlative filter, target quality parameter evaluation and radar self-adaptive control. Aiming at a target with different characteristics, the invention acquires the integrated optimization of the detection performance and the resolution performance as well as the detection performance and the tracking performance and forms a self-adaptive marine radar detection system facing to the target.

Description

technical field [0001] The invention relates to the technical field of marine radar, in particular to a marine radar detection system and a detection method thereof. Background technique [0002] Nautical radar is the basic means of guaranteeing the safety of ship navigation. In the use of marine radar, according to the range setting and the setting of working state parameters, the detection performance of the radar can be changed according to the requirements. These adjustable and settable working state parameters are mainly: the pulse width and pulse repetition frequency of radar signal transmission, the gain and bandwidth of signal reception, and the parameter settings of various signal detection processing and target tracking processing in ARPA radar terminals. The performance of radar observation depends on these working state parameters. However, these working state parameters of marine radar are the same for all targets in the observation environment around the radar...
