Monostatic radar with the rapid development of Electronic Science and Technology , there are a lot of limitations , the small dual multi - radar and more widely , the increasingly urgent demand . Bistatic radar compound is particularly suitable for the air traffic control system , high efficiency of monostatic radar guns , good accuracy ; addition bistatic radar target high resolution capability than single radar analysis of the vertical structure of the atmosphere . location, the vertical structure of the atmosphere is the focus of the meteorological analysis . Detection of meteorological elements , mainly used in small-scale control of the radar antenna receiver . Using TI dedicated to the motor control of the digital signal processor TMS320LF2407A to control the servo system of the radar antenna , it can receive the echo signals from the target object . The DSP chip integrated motor control necessary for the multi-channel PWM signal generator ; analog / digital conversion ; serial communication , and greatly improve the flexibility of the system , the digital control of the motor control is very suitable for the requirements of the motor servo control system and low-cost . The article , based on elaborate radar antenna control , describes the characteristics of the digital signal processor , and focus described how to build a complete the VVVF controller to control the radar antenna servo system . The detailed radar antenna controller design method , including the control system design principles, the various parts of the hardware circuit , software design using PWM technology and related algorithms , the structure is simple and easy to use for small multi- primary radar transmit beam -based the radar receiver, and the completion of the tracking control can be real-time feedback . In order to improve the control performance , the end of the article use the The SIMULINK simulation tool for the the entire PWM process and asynchronous motor control system simulation analysis , to verify the feasibility of the system design , and proposed the idea of the system is further improved .
