Description

Technical Field

[0001] The invention relates to the field of radar detection, and in particular to a large-scale digital array channel rapid monitoring module. Background Art

[0002] The digital beamforming (DBF) system is a key subsystem in digital array radars that can achieve simultaneous multi-beam scanning. Channel monitoring is an important function in the DBF system. The DBF system receives channel data from the array monitoring network, extracts each channel data, and packages and outputs it. It is the main way to evaluate the transmission status of the array channel.

[0003] The traditional channel monitoring method is to monitor a single channel within a frame period. For small-scale digital arrays, the number of channels is small, and the time required to complete a full array channel monitoring is within an acceptable range. For large-scale digital arrays, the number of channels is in the tens of thousands. Using the traditional channel monitoring method, it takes several hours or even dozens of hours to complete a full array channel monitoring. This is unacceptable in engineering applications and seriously limits the debugging efficiency of the product. With the increase in array size and integration, the number of array channels is increasing, and the traditional channel monitoring method is no longer suitable. It is necessary and of great significance to design a fast channel monitoring method. Summary of the invention

[0004] In order to solve the existing technical problems, the present invention provides a large-scale digital array channel rapid monitoring module.

[0005] The specific contents of the present invention are as follows: a large-scale digital array channel fast monitoring module, comprising: a timing and data separation module, a parameter management module, a channel data extraction module and a channel data packaging output module. First, a frame structure is designed to monitor each channel. The channel monitoring data is sent to the timing and data separation module. The timing and data separation module separates the required data from the channel data and sends it to the channel data extraction module. The parameter management module is used for parameter configuration and management. The channel data extraction module receives the configuration parameters sent by the parameter management module, extracts each input channel data and sends it to the channel data packaging output module. The channel data packaging output module caches and packages the extracted multi-channel data for output.

[0006] Furthermore, the designed frame structure includes N subsequences, each sequence monitors one channel, and N subsequences in one frame can monitor N channel data, where N is a positive integer greater than 1.

[0007] Furthermore, the data separated by the timing and data separation module includes: a frame start timing signal, a frame end timing signal, channel data, and a channel data valid signal, wherein the frame start timing, channel data, and channel data valid signal are sent to the channel data extraction module.

[0008] Furthermore, the timing and data separation module copies the channel monitoring frame data into two copies, one for timing signal matching to parse out the frame start timing signal and the frame end timing signal, and the other for parsing out the channel data and the channel data valid signal based on the timing information and the data valid information.

[0009] Furthermore, the parameters managed by the parameter management module include: the number of subsequence points, the starting point of extraction and the ending point of extraction.

[0010] Furthermore, the channel data extraction module extracts the channel data at the corresponding position for each input channel data according to the extraction start point and extraction end point parameters.

[0011] Furthermore, the channel data extraction module extracts the channel data at the corresponding position, including: the channel data valid signal is sent to the counter for counting processing, and the frame start timing signal is sent to the counter for clearing the counter; the channel data valid signal is intercepted from the channel data valid signal according to the counter information, the number of subsequence points, the extraction start point and the extraction end point by the channel data valid interception module (extraction end point-extraction start point), and the channel data is delayed and output to the channel data packaging output module.

[0012] Furthermore, the channel data packaging and output module receives the extracted N channel data and their valid signals in sequence and caches them, and when the frame end timing signal arrives, the monitoring data of each N channel is packaged and output according to the agreed format.

[0013] The present invention adopts a method of extracting and caching channel data from multiple subsequences and then uniformly packaging and outputting them, which can improve the array channel monitoring efficiency by dozens of times and shorten the full array channel monitoring time of a large-scale digital array from several hours to several minutes, thus meeting product debugging requirements.
