The radar fight environment is complicated (various electromagnetic interference and countermeasure environments, complex geographic environments and meteorological environments), the detection mode is diversified and various functions are integrated, and higher requirements are put on the functions and performances of radar equipment. The complicated electromagnetic environment requires the radar system to have the capability of improving the detection capability of targets according to the actual background and through complex means such as statistical learning, self-adaptive processing and the like, different detection objects and various complicated detection tasks require the radar to flexibly configure resources, expand functions and working modes, and various platforms such as foundations, carrier-borne, space-based and the like require the radar system to realize the integration of multiple functions such as active/passive detection, multi-source signal/information fusion and the like. Meanwhile, in order to combat new threats continuously appearing, radar systems are required to adapt to complex dynamic environments and task demands, new algorithm technologies are continuously developed, and the performance of the radar systems is rapidly improved. In recent years, with the rapid development and maturity of technologies such as digitalization, high-performance real-time computing and software, the radar system technology enters a new development period, and the development trend makes main components of the radar system have the capability of defining, developing and configuring through a software mode, and meanwhile, the progressive maturity of middleware technology and system optimization integration technology makes the radar system have the capability of decoupling bottom-layer hardware and upper-layer task software, so that a "software radar" technology is generated.

The existing radar signal processing system adopts a customized design development mechanism, namely, a specific processor and a board card are selected and designed according to specific radar tasks and requirement indexes, and application software is developed directly based on a development environment appointed by a bottom hardware platform and a processor thereof, so that a specific signal processing system is realized. The implementation mode adopts a design development mode that radar task requirements are strongly bound with a processing system and software and hardware are tightly coupled, so that the existing radar signal processing system has the following problems: the functions and performances of the signal processing system are solidified, so that the system cannot be dynamically reconstructed or the processing flow, the processing mode and the processing parameters can not be adjusted according to changeable requirements and environments; secondly, the development difficulty is high, the development period is long, a design developer needs to go deep into the bottom details such as storage, interruption and communication of each processor, and once a certain key link has a problem or a fault, the serial research and development flow can cause the delay or the stagnation of the overall design and development work of the system; and thirdly, the system has large and difficult maintenance and upgrading workload and lacks system inheritance, flexibility and technology updating capability.

In summary, the existing radar signal processing method has the problem of low efficiency.

It is noted that the terms used herein are used merely to describe particular embodiments and are not intended to limit exemplary embodiments in accordance with the present application and when the terms "comprises" and/or "comprising" are used in this specification they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.

In the several embodiments provided by the present invention, it should be understood that the disclosed apparatus, system and method may be implemented in other manners. For example, the system embodiments described above are merely illustrative, e.g., the division of the modules is merely a logical function division, and other manners of division may be implemented in practice.

The modules described as separate components may or may not be physically separate, and components shown as modules may or may not be physical units, may be located in one place, or may be distributed over multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

In addition, each functional module in the embodiments of the present invention may be integrated in one processing unit, or each unit may exist alone physically, or two or more units may be integrated in one unit. The integrated units can be realized in a form of hardware or a form of hardware and a form of software functional modules.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims shall not be construed as limiting the claim concerned.

Furthermore, it is evident that the word "comprising" does not exclude other elements or steps, and that the singular does not exclude a plurality. Multiple units or systems as set forth in the system claims may also be implemented by means of one unit or system in software or hardware. The terms first, second, etc. are used to denote a name, but not any particular order.

Finally, it should be noted that the above-mentioned embodiments are merely for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
