[0002] Digital array reconnaissance systems must scan the operating frequency domain by changing the receiving frequency and switching the beam direction to scan the operating airspace, searching for signals within a specified spatial frequency range. Scanning the operating airspace is typically achieved by sequentially directing the beam toward pre-arranged search beam centers. Currently, reconnaissance systems typically arrange search beams according to fixed rules and parameters, and pre-allocate memory to store beam data for use during searches. Existing reconnaissance systems are unable to adapt to changes in beam arrangement rules without software modifications. Because the beam widths of various frequency bands vary, separate memory must be allocated for storing beam data for each band. When the reconnaissance system operates over a wide frequency range, insufficient computer memory may cause the system to malfunction. Summary of the Invention

[0028] Example 2, as Figure 2 、 Figure 3 as well as Figure 4 As shown: S10: Establish a signal search wave position arrangement model.

[0029] The digital array reconnaissance system needs to traverse the frequency domain and the spatial domain during the search process. The frequency domain is divided into several frequency bands with the system receiving bandwidth as the step, and the search center frequency and beam width of each frequency band are different. For each frequency band, the spatial range (including azimuth range and elevation range) is divided into several search wave positions according to the azimuth interval and elevation interval, and each search wave position is allocated a search beam to cover it. The wave position arrangement within the spatial range has rectangular arrangement (such as Figure 2 As shown), triangular arrangement (as shown Figure 3 In order to take into account various arrangement forms, the concept of "virtual and real nodes" is introduced to divide the airspace into plane grid areas. The four corner vertices of each grid are the center arrangement points of the wave position. The arrangement points of the actual arranged wave position are real nodes, and the arrangement points of the unarranged wave position are virtual nodes. This is used to describe the search wave position arrangement, as shown in Figure 4 shown.

[0030] The signal search wave position arrangement model consists of the wave position arrangement models of all frequency bands. The wave position arrangement model parameters of each frequency band include: Starting frequency, that is, the lower frequency limit of the current frequency band; End frequency, that is, the upper frequency limit of the current frequency band; Azimuth interval, that is, the azimuth step value between two adjacent columns of arrangement points; Pitch interval, that is, the pitch step value between two adjacent rows of arrangement points; Step value, starting from the first arrangement row, the difference between the row numbers of two adjacent arrangement rows with real nodes; Odd-numbered arrangement row starting column: The arrangement rows with real nodes are sorted from small to large according to the row number. The rows with odd positions are odd-numbered arrangement rows, and the arrangement column to which the first real node in the arrangement row belongs is the odd-numbered arrangement row starting column; Odd-numbered row and column step value: the difference between the column numbers of two adjacent real nodes in an odd-numbered row; Even-numbered arrangement row starting column: The arrangement rows with real nodes are sorted from small to large according to the row number. The ones with even positions are even-numbered arrangement rows, and the arrangement column to which the first real node in the arrangement row belongs is the even-numbered arrangement row starting column; Even-numbered row and column step value: the difference between the column numbers of two adjacent real nodes in an even-numbered row.

The beamformation search scheduling module responds to the search spatial frequency domain setting commands sent by the search control module, performs beamformation within the search spatial frequency domain based on the beamformation model parameters, and schedules the beam for signal search.

[0035] S40: Edit and issue a command for searching the empty frequency domain.

[0036] The user sets the search frequency and airspace range of the digital array reconnaissance system through the search control module, generates and issues the search airspace setting command. The specific process is as follows: Enter the search start frequency; Enter the search end frequency; Enter the search starting azimuth; Enter the search end azimuth; Enter the search starting pitch angle; Enter the search end pitch angle; The edited search space frequency domain setting command is published to the wave position search scheduling module.

[0037] S50: Perform signal search scheduling.

[0038] The beam search scheduling module responds to the search space frequency domain setting command, schedules the digital array reconnaissance system beam, and searches for signals in the specified space frequency domain. The specific process is as follows: a) traversing the wave position arrangement model parameters of each frequency band of the digital array reconnaissance system, and selecting a frequency band whose start and end frequency range overlaps with the search frequency domain range as the frequency band to be searched; b) Select the first frequency band to be searched, starting from the lower left corner of the plane grid area of ​​the beam position arrangement, and traverse all the arrangement points in the order of traversing from left to right column by column within the row, and then traversing from bottom to top row by row. For each real node, use the average of the starting frequency and ending frequency of the frequency band to be searched as the center frequency, assign the beam to the azimuth and pitch corresponding to the real node, and perform signal search; c) After completing the search for all real nodes in the current frequency band to be searched, switch to the next frequency band to be searched and continue the signal search; d) Repeat step c) until all frequency bands to be searched are searched; e) Repeat steps b) to d) until the search is terminated.
