Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] In order to improve the intelligence of the jammer, the invention adopts the SOPC technology to realize the real-time generation and configuration of the jamming decision parameters.

[0018] SOPC is a Programmable System on Chip. It is a special embedded system that not only can complete the main logic functions of the entire system by a single chip, but also makes the design more flexible due to its programmable features, which can be tailored, expanded, and upgraded, and has software and hardware systems. programming function.

[0019] The present invention selects the FPGA chip of Xilinx Company, uses an embedded development kit (EDK, a development tool), and realizes SOPC design by embedding a soft processor core (MicroBlaze, a product provided by Xilinx Company) in the FPGA. This design method can build a general-purpose platform for inte...

Abstract

The invention belongs to the technical field of electronic countermeasure and particularly relates to a jamming decision device based on SOPC (System-on-a-Programmable-Chip), so as to improve the intelligent degree of a jammer and improve the jamming decision device. An FPGA is used for building the SOPC (System-on-a-Programmable-Chip), jamming decision is carried out in real time, and the radar jamming function is realized. The following modules such as a soft-core processor, a program RAM, a data RAM, a jamming algorithm module, an IIC and a GPIO in the FPGA are realized. The testing result shows that the SOPC platform achieves expected functions, jamming decision parameters can be configured in real time, and the scheme is feasible. The jamming decision technology based on the SOPC is applied to the jammer, and the radar docking test result shows that intelligent jamming on the radar can be realized by the product.

Description

technical field [0001] The invention belongs to the technical field of electronic countermeasures. Background technique [0002] This jamming decision-making technology based on a Programmable System-on-a-Programmable-Chip (SOPC) comes from the design of jammers. The jammer can suppress and spoof the radar and reduce its ability to track and identify real targets. In the traditional design, the interference decision-making parameters are pre-configured, and the parameters are calculated according to the loaded data, and the interference decision-making parameter table is generated in advance, and the interference decision-making parameter table is configured according to the generated parameter table. [0003] In this way, since the interference mode is fixed in advance, it cannot meet the requirements of real-time intelligent interference. Therefore, there is a need for a jammer that can intelligently implement jamming according to the type of radar and the external envir...
