In a system such as ELINT or RWR used in a conventional electronic warfare receiver, the process of signal collection, analysis, identification, and generation of threat information has been performed in a unified sequence. Accordingly, there is a waiting time without signal analysis and identification until the collection is completed.

Various embodiments of the present specification may be implemented by an electronic device including at least one processor, at least one memory, and at least one transceiver. Here, the electronic device may be implemented as a wireless device illustrated in FIG. 10 . Hereinafter, a subject performing the signal processing method according to various embodiments of the present specification may be realized by at least one processor (102, 202 of FIG. 10 ) included in an electronic device.

1 is a flowchart of a signal processing method according to an embodiment of the present specification.

In an embodiment, the at least one processor may set a search band list having a plurality of frequency search bands in the receiver (S101).

S101 is a step of setting data of a frequency search band to be traversed in the receiver, which is a pre-procedure for performing S107.

In an embodiment, the at least one processor may allocate a predetermined number of tasks related to signal processing to the memory ( S102 ).

In this case, the assigned task may be switched to an idle state by at least one processor. In one embodiment, the at least one task may be a task for collecting or processing a signal. At least one task may have an idle state and a run state as state information. The run state may include at least one of a signal collection state, an analysis state, an identification state, and a threat information generation state.

Meanwhile, a detailed description of S102 will be described later with reference to FIG. 2 .

In an embodiment, if signals for at least some of the search bands included in the search band list are not collected, the at least one processor performs at least one of a predetermined number of tasks to collect signals in at least some of the search bands. of the idle task can be detected (S103: NO, S104). If signals for all search bands included in the search band list are collected, at least one processor ends the signal collection and processing procedure (S103: YES, end)

In an embodiment, when at least one idle task is detected, a signal collection and processing operation may be performed using the detected idle task (S105: YES, S106, S107, S108, S109, S110). Meanwhile, if the idle task is not detected, the at least one processor returns to S103 again.

The signal collection and processing operations may include a) signal collection (S107), b) signal analysis (S108), c) signal identification (S109), and d) threat information generation (S110) operations. In the signal collection operation, the at least one processor may transmit identification information of the search band to the receiver to receive digital signal data to support collection control. In the signal analysis operation, the parallel signal processing apparatus may obtain the specification characteristic of the signal emitted from the threat based on the specification characteristic or pattern of the threat signal. In the signal identification operation, the at least one processor may extract information associated with an emitter that matches at least one of a specification characteristic of the received signal and a specification characteristic of a signal recorded in the threat library. In generating threat information, the at least one processor may generate threat information based on information related to the extracted emitter.

Meanwhile, in an embodiment, when the at least one processor collects the signal in S107 , it may analyze the signal together with traversing the search bands included in the search band list again.

As such, the parallel signal processing method according to an embodiment of the present invention does not perform the operations of collecting a signal based on the entire frequency search band, analyzing, identifying, and generating threat information in a single sequence, unlike the conventional technique. Instead, after the signal is received, analysis of the corresponding signal is performed, and at the same time, it is determined whether the entire search band has been traversed so that the next search band can be collected.

Meanwhile, in S110, at least one processor generates threat information based on information related to the identified emitter. As a result, if it is a known emitter, it extracts the threat information loaded with the emitter from the threat library, , if it is an unknown emitter, it is judged as an unknown threat. Then, when S110 is finished, the at least one processor returns to S103 and either ends the signal collection and processing procedure according to whether the collection of signals for the entire frequency search band is completed, or proceeds to S104 again.

FIG. 2 is a flowchart for describing step S102 of FIG. 1 in detail.

In an embodiment, the at least one processor may receive the number of tasks to be generated through a user interface or a transceiver ( S201 ).

In other words, the signal processing device may receive in advance the number of tasks to be generated for collecting, analyzing, identifying, and generating threat information.

In an embodiment, the at least one processor may allocate a number of tasks to the memory corresponding to the number of received tasks ( S202 ).

Here, allocating a task refers to allocating at least a part of a task stack size, a task priority, a task identification information (ID), and a task name.

In one embodiment, the assigned task may be switched to an idle state (S203).

As described above, the state of the task may have an idle state and a run state, wherein the run state may include at least one of a signal collection state, an analysis state, an identification state, and a threat information generation state. Meanwhile, in this specification, the idle state may be referred to as an initialization state.

In S203 , the at least one processor may convert the states of all tasks to the initialization state.

Further, in one embodiment, the at least one processor may initialize variables related to memory, signal analysis, and signal identification of each task after or immediately after transitioning the assigned task to the idle state.

In an embodiment, when all tasks allocated to the memory are switched to an idle state, and variables related to memory, signal analysis, and signal identification are initialized, at least one processor may thereafter select one of the search bands included in the search band list. At least some search bands in which signals are not collected may be checked (S204: YES, S103). If such variables are not initialized or if the task is not switched to the idle state, it returns to S203 (S204: NO).

FIG. 3 is a reference diagram for describing S104 of FIG. 1 in detail.

In an embodiment, the at least one processor may transmit a search request for an idle task to all tasks allocated to the memory ( S301 ).

In other words, the at least one processor may determine the status of the tasks in order to select an operable task.

In one embodiment, the at least one processor may receive status notification messages from each of all such tasks (S302a, S302b, S302c, S302d, S302e).

Here, the status notification messages are divided to correspond to respective status information of the tasks Ta, Tb, Tc, Td, and Te. For example, in the initialization state, the task transmits a message indicating the initialization state, in the signal analysis state, the task transmits a message indicating the signal analysis state, and in the signal identification state, the task transmits a message indicating the signal identification state, And in the threat information generation state, the task transmits a message indicating that the threat information generation state is present to at least one processor.

Thereafter, the at least one processor may detect the at least one idle task based on at least one of the status notification messages. Here, the status notification messages are transmitted from the task in response to the search request, and when a message notifying the initialization state is received, at least one processor may determine that the task associated therewith is an idle task.
