Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] At the sending end, the binary bit stream is first mapped into decimal data S i , and at the same time perceive the surrounding electromagnetic environment to obtain a set of frequency energy efficiency sequences. This set of sequences sets the occupied frequency band to 0, so it can actively avoid the interference frequency band. According to the method introduced above, the required random phase is generated, multiplied by the spectrum energy efficiency sequence, and then the required basic modulation waveform FMW can be obtained through scaling and IFFT; then the data is modulated onto the FMW by CCSK. The tDCS signal frame is then pulse-modulated to replace a single pulse within a pulse repetition period with a frame of tDCS symbols. Finally, the generated signal is transmitted through the transmitting antenna.

[0043] At the receiving end, afte...

Abstract

The invention belongs to a radar and communication integrated scheme based on a radar launching mode of a TDCS (Transform Domain Communication System), introduces the TDCS and is particularly applicable to a super-resolution radar and communication integrated system requiring self-adaptive frequency conversion and initiative anti-interference as well as low interception rate. According to a super-resolution radar and communication integrated method based on TDCS radar launching mode, a launching signal can self-adaptively adjust the launching frequency, signal interference is initiatively avoided while the spectrum efficiency is improved, and besides, the demand for low acquisition probability is also met because of CCSK (Cyclic Code Shift Keying) modulation.

Description

technical field [0001] The present invention belongs to the radar communication integration scheme based on the radar transmission mode of the transform domain communication system (Transform Domain Communication System, TDCS), introduces the TDCS system, and is especially suitable for super-resolution requiring adaptive frequency conversion, active anti-jamming and low interception rate In the integrated radar communication system. Background technique [0002] With the continuous development of science and technology, in order to meet the military needs in the new battlefield environment, the number of electronic equipment installed on the same combat platform is gradually increasing, resulting in increased system volume, energy consumption and weight, complex operations, increased redundancy, and gaps between equipment. Increased electromagnetic interference, system performance degradation and many other problems. Using a multi-functional integrated electronic system is ...
