The Platform Design Of Radar Signal Processing Based On TIC6678

In the modern war research onboard radar signal processing is of great importance. It can detect the enemy's target and carries on the precision. By using the corresponding detection equipment to receiving the positioning of the target signal and the corresponding signal and data processing, we can complete the monitoring area of target detection, location and tracking.Onboard radar system usually uses the transmission and reception of broadband signal, and then uses the corresponding to extract the information from the target echo signal processing module, and being based on this information to determine the differences between different goals and then to identify the target of interest.Since the 90 s, with the aid of the high speed development of large scale integrated circuit,DSP and FPGA technology also increase rapidly, embodied in its various performance continuously strengthen. At the same time, all kinds of demand has prompted radar performance enhances unceasingly. At the same time, the development of radar signal processing technology, also has a higher request to the processor performance. So some processors are still can't meet the requirements of some based on various complex algorithm.This article is based on TMS320C6678 as the core of the digital signal processing platform,to design the software implementation of the conventional radar signal processing algorithm. Paper analyzed under the condition of narrow band radar signal processing technology and use MATLAB to generate simulated target echo data to process more radar simulation, and introduces the TMS320C6678 resources and SRIO communication interface. So by multi-core parallel computing can usually satisfy radar signal processing more complex algorithm on DSP computing requirements.Due to the particularity of radar signal processing algorithm, thus in software we can use the data flow model and parallel model to solve the problem of the multi-beam large computational complexity in signal processing. In this mode, some of the core is divided into two groups, each group of the nuclear power a beam processing tasks independently,equivalent to a data flow model, and the parallel group can finish the multi-beam processing.Larger points are used in wideband radar signal processing of constant false alarm processing.This paper introduces a two-dimensional constant false alarm processing algorithm, which can better achieve the goal of detection.
