Direction finding device and method for radar interference test drilling system

Abstract

The invention discloses a direction finding device and method for a radar interference test drilling system, the device comprises a direction finding device and a display control unit, the direction finding device comprises a receiving antenna, a frequency conversion unit, a parameter measurement and direction finding unit and a timing system positioning and orientation device which are arranged in an antenna pedestal, and the antenna pedestal is arranged on an azimuth-pitching two-dimensional turntable; the parameter measurement and direction finding unit adopts an FPGA + DSP architecture to measure and analyze the digital signal and extract a radiation source target; and the display control unit is used for controlling the direction finding equipment and displaying information. When the direction finding device is switched from a search mode to a tracking mode, data interruption triggering between the FPGA and the DSP unit is changed into timing triggering interruption, the DSP unit is provided with two tracking special data areas used for dual-core ping-pong data switching, a core 0 receives data, and a core 1 processes the data and performs pulse matching with the azimuth direction as the reference. The universality, the flexibility and the real-time performance of the direction finding device are improved, and an external interface is simplified.

Description

technical field [0001] The invention relates to the technical field of electromagnetic environment signal monitoring, in particular to a direction finding device and method for a radar interference test and exercise system. Background technique [0002] On the current and future battlefields, the use of new technologies and new equipment for electronic warfare is changing with each passing day, which has an increasing impact on combat guidance, combat methods, and combat command, and has become one of the key factors in winning the war. In the integrated electronic warfare system, electronic jamming is the main content of electronic warfare, and electronic reconnaissance is the premise and foundation of organizing the implementation of electronic jamming and destruction. [0003] With the development of electronic warfare, the current electronic warfare technology not only faces electronic threats such as broadband, high density, parameter agility, multi-mode compounding, an...
