A Radar Signal Processor External Communication Control System

Abstract

The invention discloses a radar signal processor external communication control system. The radar signal processor external communication control system comprises an FPGA, which comprises a transceiving module used for interface management and transceiving of serial communication; a DSP, which is connected with the FPGA, and is used for control of transceiving time sequences, processing of communication protocol content, and configuration of communication parameters; and a connector, which is in a bidirectional connection with the FPGA. The radar signal processor external communication control system is advantageous in that the internal resources of the FPGA and the DSP are fully used, and a special 422 communication chip is not required, and corresponding peripheral circuit design is reduced, and therefore the communication control of the signal processor over other components of the radar is realized stably, and power consumption of a single device and device costs are reduced; parameter configuration is realized, and the requirements of the system on the diverse working modes are satisfied.

Description

technical field [0001] The invention relates to the field of radar digital signal processing, in particular to an external communication control system of a radar signal processor. Background technique [0002] The components of the existing radar system are often designed according to the task requirements, and the working mode is relatively single. The design of the control signal line between the signal processor and other components of the system is mostly fixed connection. With the diversification and compounding of the radar working system and the complexity of the working process of the radar system, the working mode of each component is no longer a single or fixed mode, and the requirements for the components are increasing; correspondingly, the signal processor and other components of the system The number of control signals between the wires has also increased significantly, and in order to avoid the mutual interference of different speeds and different types of co...

[0002] The components of the existing radar system are often designed according to the task requirements, and the working mode is relatively single. Most of the control signal lines between the signal processor and other components of the system are designed in a fixed connection mode.

With the diversification and compounding of the radar working system and the complexity of the working process of the radar system, the working mode of each component is no longer a single or fixed mode, and the requirements for the components are increasing; correspondingly, the signal processor and other components of the system The number of control signals between the wires has also increased significantly, and in order to avoid the mutual interference of different speeds and different types of control signals between the bonded wires, the form of shielded wire isolation is often adopted. The traditional connection method of control signal wires makes the volume of the connector become An important restrictive factor in system design, which brings many unnecessary troubles
