Abstract

The invention discloses an SOC (system on chip)-based radar system, which is characterized in that a control module receives a data packet sent by an upper computer to obtain a corresponding beam information code, a signal parameter and a passband control instruction, a first FPGA (field programmable gate array) module generates linear frequency modulation signal data, a filter module filters the linear frequency modulation signal data to obtain a transmitting signal, and the transmitting signal is transmitted to the upper computer. The radio frequency transceiver module sends a transmission signal to the antenna module or sends an echo signal received by the antenna module to the second FPGA module, the beam forming module controls the beam direction of the antenna module according to beam information coding, and the antenna module sends the transmission signal according to the beam direction. Or an echo signal received from the outside is sent to the radio frequency transceiver module. According to the invention, flexible switching of multiple radar modes can be realized, the system is easy to adapt to a complex use environment, is easy to miniaturize and low in cost, is convenient to install and use, and expands the working places and modes of the radar. The method is widely applied to the technical field of radars.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to an SOC-based radar system. Background technique [0002] Radar is widely used in battlefield operations, weather detection, traffic navigation and agricultural production. With the diversification of application requirements, new requirements are put forward for radar in terms of power consumption, volume, cost, and performance. Features; mmWave detection applications hope to have a simpler architecture and lower complexity so that they can be implemented in high frequency bands. As common problems, high cost, low integration and large volume have become the reasons that restrict the development of radar. Designing and developing a new type of phased array with low cost, low power consumption, high integration, small size, broadband and wide scanning angle has become one of the key technical challenges of the new generation of radar systems.
