Description

Technical Field

[0001] The utility model relates to the technical field of secondary radar, in particular to an energy-saving and stable S-mode secondary radar antenna system. Background Art

[0002] Secondary radar (SSR) is a radar system that corresponds to primary radar. Unlike primary radar, which identifies targets by reflected waves from airborne targets, secondary radar operates differently. A ground station or airborne interrogator sends an interrogation signal to an airborne target. The target's transponder then sends a reply signal, which the ground station or airborne device then uses to identify the target.

[0003] Mode S is an advanced radar interrogation system based on independent addressing and selective interrogation. It can solve the problems of signal interference, limited information coding, phantom and asynchronous response in Mode A / C, and also has great potential in data link.

[0004] The S-mode secondary extended information link places higher demands on the transmitter, requiring the transmitting components of the transmitting system to meet the working requirements of the S-mode extended information link. The transmitting components under the existing technology cannot meet the working requirements of the S-mode extended information link, and have complex structures, high energy efficiency losses, and unstable performance.

[0005] Therefore, we propose an energy-saving and stable S-mode secondary radar antenna system to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an energy-saving and stable S-mode secondary radar antenna system.

[0011] The responder is connected to the power amplifier platform, and is used to process the amplified signal, add its own specific code to the signal, and return the processed signal to the radar transmitter;

[0012] The power amplification platform includes a signal processing module, a power amplification module, a signal sending module and a feedback module;

[0013] The signal processing module is used to pre-process the signal. After the pre-processing, the signal enters the modulator for modulation and becomes a high-frequency signal;

[0014] The power amplifier module is used to amplify the high-frequency signal to give it sufficient power and intensity;

[0015] A signal sending module, used for sending the amplified signal;

[0018] Preferably, the processing speed calculation module is connected to the signal processing module, and the processing speed calculation module is used to monitor and calculate the processing speed of the signal processing module, and transmit the calculated speed data to the comparison module;

[0019] A threshold setting module is used to set a speed comparison threshold and transmit the set comparison threshold to the comparison module;

[0020] A comparison module is used to compare the calculated speed data with a set threshold;

[0021] The early warning module is used to choose whether to issue an early warning based on the comparison results.

[0022] Preferably, the responder includes a radar signal receiving module, the radar signal receiving module is connected to a signal processing module, and the signal processing module is connected to a signal return module.

[0023] Preferably, the radar transmitter includes a return information receiving module, the return information receiving module is connected to a decoding module, the decoding module is connected to a calculation module, and the calculation module is connected to an output module.

[0025] In the present invention, the beneficial effects of the energy-saving and stable S-mode secondary radar antenna system are as follows:

[0026] The power amplification platform is set up to pre-process the signal and then enter the modulator for modulation to become a high-frequency signal. Then, the high-frequency signal is amplified by the power amplification module to give it sufficient power and intensity. Finally, the amplified signal is sent to the responder through the signal sending module.

[0027] The present invention can ensure that the signal has sufficient power and intensity to meet the working requirements of the S-mode extended information chain, has good stability, reduces the cost of maintenance and replacement of components, and is more energy-efficient.
