The capabilities of receiving and identifying signals and automation function level of a radar are substantially improved through digital processing, displaying and controlling of the radar signals. The system comprises an analog/digital (A/D) conversion circuit, a programmable logic circuit, a digital signal processor (DSP), a general-purpose processor system, a display and system program software. The system has the advantages of enriching the field of radar technology, lowering the threshold of radar technology research and being capable of more effectively improving the cost performance of the radar system.
Description
Technical field
The present invention relates to the processing of a kind of navar signal digital, demonstration and control system.By digital processing, demonstration and control, increase substantially the received signal of radar and the ability and the automation function level of identification signal to radar signal.
Background technology
At present, navar has become a kind of inexorable trend to digital development.Because digitizing not only help improving Radar Signal Processing and identification key property, help the miniaturization of radar system, and help further developing of radar functions of use.The technology path of traditional digitized radar is constantly to advance on radar function module and special IC basis.Technical advantage is in this respect also monopolized by the internationally famous radar of minority enterprise always.Along with the continuous development of general-purpose computations machine technology, the utilization general-purpose computing system is created the special radar set system and has been had possibility.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of field of enriching Radar Technology is provided, reduces the threshold of Radar Technology research, improves the processing of navar signal digital, demonstration and the control system of the cost performance of radar system more effectively.
Purpose of the present invention is achieved through the following technical solutions: the processing of a kind of navar signal digital, demonstration and control system, the processing of navar signal digital, demonstration and control system are made up of A/D change-over circuit, Programmable Logic Device, DSP digital signal processor, general purpose microprocessor system, display and system program software.Wherein, the A/D change-over circuit is responsible for the radar video analog signal conversion is become digital signal, and the resolution setting of A/D conversion is more than 8.Programmable Logic Device is responsible for according to the bearing signal of transceiver and synchronizing signal radar echo signal, bearing signal, bow signal being gathered.The DSP digital signal processor is responsible for radar echo signal carried out that digital filtering, digital wave suppress, digital sleet suppresses, be responsible for display mode calculating, with the general purpose microprocessor system communication.The general purpose microprocessor system be responsible for overall coordination, the man-machine interface of radar system function and control in real time, the realization of the control of data storage, peripheral hardware and multimedia function, the general purpose microprocessor system is the ARM microprocessor.Display is responsible for showing radar signal picture, auxiliary data picture, is controlled menu screen and other pictures, satisfies the performance requirement that the radar return high-contrast shows and night, echo showed.
The present invention compared with prior art has following having a few:
The present invention not only can enrich the field of Radar Technology, reduces the threshold of Radar Technology research, and can improve the cost performance of radar system more effectively.
