Embodiment Construction

[0012] The present invention is specifically implemented from the following aspects:

[0013] 1. The system adds coding modulator, decoding demodulator and radar timing beam control to the pulse radar, and adopts FSK and OQPSK modulation and demodulation methods that have low requirements on the linearity of the power amplifier, which greatly reduces the system's requirements on the linearity of the power amplifier. In the communication mode of the radar, the coded modulator receives the information sent by the computer through the network. Under the timing control of the radar, it generates a large time-width pulse intermediate frequency communication modulation signal to replace the pulse detection signal generated inside the radar, and passes through the radar. After the frequency converter and high-power transmitter amplify, it radiates to the air. In order to ensure that the transmitting and receiving nodes can be aligned with a high probability, the sending information s...

Abstract

The invention relates to a remote high-efficiency data transmission technology of a pulse radar and a realization method thereof. In the method, a remote communication data transmission function is added in the conventional pulse radar. Through adding applications of a broadband efficient intermediate frequency coding modulator, a broadband efficient intermediate frequency decoding demodulator, radar sequence beam control, high-speed high-efficiency data transmission under a low duty ratio condition, Reed-Solomon coding and decoding under a deep saturated power amplifier, a FSK and OQPSK modulation demodulation technology and the like in the pulse radar, a multifunctional integration design based on the function of broadband efficient data transmission of the pulse radar, radar detection and communication information transmission can be realized.

Description

technical field [0001] The invention relates to a pulse radar long-range high-efficiency data transmission technology. By optimizing and improving the working sequence, timing sequence, beam resources, and waveform generation and processing algorithms of the existing large-duration pulse-based radar, the cooperative sharing of radar detection information can be realized with the minimum increase in system configuration. Background technique [0002] The radar detection system uses the reflection phenomenon of the target to the electromagnetic wave to find the target, and extracts relevant information from the target echo to obtain its spatial position, speed and other information. The purpose of communication is to exchange messages in different places. The message is first converted into various forms of electrical signals at the sending end, and then passes through various electrical channels (such as cables for wired communications, short waves, microwaves, etc. in wirele...
