Abstract

The invention belongs to the technical field of radar plot processing and especially relates to a three-coordinate monitoring radar plot processing method based on an active phased array technology system. The method is characterized by carrying out coagulation and filtering optimization processing on three-coordinate plot data through initial echo processing, plot coagulation treatment and plot filtering processing and representing the result obtained after plot processing to a user through a terminal display monitor system, thereby improving monitoring and management capability of a management department for low-altitude small targets. The initial echo processing and plot coagulation processes are spontaneous, thereby reducing influence of artificial factors on the final three-coordinatemonitoring radar plot coagulation result to the maximum degree; site optimization parameters and enable control fed back by the terminal display monitor system can further optimize plot quality, andfiltering processing is carried out on plots obtained after coagulation. The method realizes output of distance, orientation and height information of the low-altitude targets, and provides basis foridentification and supervision of low-altitude slow and small targets for the traffic control department.

Description

technical field [0001] The invention belongs to the technical field of radar spot processing, in particular to a three-coordinate surveillance radar spot processing method based on an active phased array technology system. Background technique [0002] Phased-array radar is one of the most advanced radar systems at present. Phased-array radar uses electricity to control the change of radar beam pointing for scanning, and obtains the most reasonable and adaptive use of radar time and energy resources. Complete the search mission in the guarded airspace. Phased array radar is divided into two types: active phased array and passive phased array. The radiated energy of active phased array radar is generated on the antenna array without high-power transmitter. The feeder network is simple and reduces the complexity. The loss of the transmitting and receiving channel improves the efficiency of the radar system by synthesizing the directional beam coherently through the space of t...
