The invention relates to a system and a method for monitoring a moving target on the ground by a marine radar. The system comprises the marine radar, a radar signal interface and a target monitoring processor (a computer), wherein the marine radar transmits a compressed microwave probe pulse and receives a detection echo from a monitoring area; the radar signal interface realizes type conversion, digital acquisition and USB digital transmission of a radar signal; and the target monitoring processor receives and processes radar image data through a USB interface and monitors the moving target on the ground. The method comprises steps as follows: frame formatting of radar signal digital acquisition data, detection of real-time dynamitic reference image, difference image and the moving target and detection and alarming of a space shielding image and the moving target. The ground moving target monitoring system suitable for safety monitoring of various lands is formed by utilizing the general marine radar and a corresponding signal receiving and processing method. By means of the monitoring system and the method, the marine radar can be applied to the land echoing environment, and the safety efficiency of the marine radar applied in the land is improved.
Description
Technical field [0001] The invention relates to the technical field of navigation radar and the field of safety monitoring, in particular to a navigation radar ground moving target monitoring system and a monitoring method thereof. Background technique [0002] There are many sensor technologies for land environmental target monitoring, including visible light, infrared, ultrasound, etc., but they all have their limitations, especially under severe weather conditions, the detection performance and reliability are limited. As a microwave sensor, radar has irreplaceable detection characteristics such as optical sensors. Considering that some special radars suitable for land monitoring have complex equipment and high maintenance costs, the present invention adopts general economical civil navigation radars. Navigation radar is the basic guarantee for the safety of ship navigation, and it has always played an important role in the field of navigation. As a general-purpose civil shi...
