1. Online explanation [click here to view the details of the plan].

Anti-interference refers to the impairment of the reception of a useful signal. Anti-jamming is a system or technology used to counter any interference in communications or radar operations. Academic Definition:

1) Combined with the characteristics of the circuit to minimize interference. (2) It means that the device is able to prevent electromagnetic interference acting on the device through the antenna input, the housing of the device, and along the power line.

For example, various improved algorithms based on space-time adaptive signal processing; Multi-carrier phase coded signal form based on waveform design; Score low-order statistics; Time series analysis; system identification, etc.

Advanced radars usually adopt a series of new technologies and systems, such as fully coherent, all-solid-state, ultra-low sidelobe antennas, digital beamforming, pulse compression, frequency agility and other advanced technologies.

Embedded bull's nose] radar anti-jamming, new system radar.

The current research on anti-jamming technologies mainly includes:

First, design anti-jamming radar waveforms, such as linear frequency modulation, multiphase coding and multiple modulation composite forms;

Second, in the antenna design, ultra-low side lobe, side lobe cancellation and other technologies are adopted;

(3) the adoption of measures such as frequency diversity, frequency agility and the opening up of new radar operating frequency bands;

Fourth, in the polarization domain, technologies such as full polarization diversity and adaptive polarization agility are adopted;

5. Design anti-interference circuits, such as wide-limit-narrow circuits, constant false alarm circuits and automatic gain control circuits;

Sixth, the space-time adaptive signal processing technology is adopted.

These anti-jamming technologies are used in all parts of radar antennas, transmitters, receivers, signal processing, and so on.

Anti-interference measures applied to antennas: low sidelobe transmitting antennas, low sidelobe receiving antennas, narrow beam, high-gain antennas, sidelobe blanking and cancelling technology;

Anti-interference measures applied to the transmitter: frequency agility, frequency diversity, waveform agility, pulse compression, optimal waveform selection;

Anti-jamming measures applied to receivers: constant false alarm handling, wide-limit-narrow receiver; Anti-interference measures applied to signal processing: digital coherence, MTI MTD PD;

Anti-jamming measures for comprehensive countermeasures: the combination of multiple anti-jamming technologies, multi-standard radar networking, flexible tactical actions, etc.

No matter what you do, you have to drill down, be distracted in the face of all kinds of distractions, be consistent, and put yourself 100% into your work.

A factory is recruiting quality inspectors online in CITIC Selling, and Xiaozhi, who has just lost his job, decides to sign up. Xiao Zhi passed the initial test, and three days later ushered in the retest.

More than 20 people came to the interview, and the company only recruited 4 people, Xiao Zhi thought, it must be the company's reputation and the acceptable salary that attracted them.

The examiner takes out a company promotional video and asks the candidate to read it in 30 minutes, and writes a 200-word reading experience in the most concise language, and the company leader will then interview each student.

There was an uproar in the examination room, some people clamored for the examiner to explain the reason, some said that the personnel had already been decided, and some people were angry and wanted to leave.

The examiner calmly said that in fact, these 30 minutes were specially arranged by the company to test everyone's ability to resist interference.

The examiner whispered: We scheduled 4 quizzes in 30 minutes. The first time was in the 5th minute, when the examiner was walking around the examination room and found that more than 10 candidates looked up at least twice at the examiner; The second time was in the 10th minute, when the examiner was outside and another staff member was making a loud noise, and as a result, 7 more people noticed the noise for no less than 5 seconds.

In the 20th minute, the examiner played ** in the classroom, deliberately pretending to be the chairman of the board of directors, we found that 85% of the comrades put down the information, listened attentively, the last time, in the 25 minutes after the end of the exam, the microphone we teased fell off the table, made a loud noise, at this time, you have completed your homework and your performance is different: some scream loudly, some joke with each other, and some well-wishers set the microphone for us.

Your performance has all entered the camera above the classroom, and according to the statistics of the backstage staff, only the people with the number 21 are the most resistant to interference, and basically do not care or pay attention to the off-site situation, so we decided to hire them last.

Finally, the examiner told everyone that as a quality inspector, they need 100% anti-interference ability, and they can really be distracted and focused on their work. Desertion, or deviating one's gaze from the "track", can allow a substandard product to escape from a high-speed pipeline, even if it is just one, and it will bring 100% loss to the company.
