2. Description of the Related Art A radio wave detection device is a device that receives a radio signal transmitted from a radio wave source such as a radar transmitting station and searches for the radio wave source based on the received signal. When the radio wave detection device receives pulse signals transmitted from multiple radio wave sources, it is necessary to classify the received pulses for each radio source in order to analyze the received pulses and search for the radio source. is there. For this reason, the radio wave detection device includes a signal classification processing device for classifying received pulses for each radio wave emission source.

FIG. 8 is a block diagram showing a configuration example of a conventional radio wave detection device. 1 in the figure is pulse group data,
2L is a signal classification processing device, 20 is a frequency classification processing unit, 2
1 is a TOI (Time Of Interval) classification processing unit, 22 is T
OA (Time Of Arrival) classification processing unit, 30 is an antenna, 31 is a radar receiving unit, 32 is an antenna driving unit, 33
Is a data generation unit.

[0004] The antenna 30 receives a pulse signal transmitted from an unknown radio wave emission source and outputs a received pulse signal. The radar receiver 31 amplifies the received pulse signal,
Performs reception processing such as demodulation. The antenna driving unit 32 drives the antenna 30 to control the receiving direction, and outputs data indicating the arrival direction of the pulse signal to the data generating unit 33. The data generating unit 33 generates pulse group data 1 based on the pulse signal from the radar receiving unit 31 and the azimuth data from the antenna driving unit 32.

[0005] The pulse group data 1 is composed of data relating to a plurality of pulse signals (pulse groups) received by the radio wave detection device, and is held in a data storage device. Each data is composed of a frequency, a pulse width, a pulse arrival direction, and a pulse arrival time for each reception pulse, and is arranged in the pulse arrival time (TOA), which is the reception time of the pulse signal. That is, the pulse group data 1 is data in which all the data of the received pulses are classified and arranged by the data generation unit 33 based on the pulse arrival times.

The signal classification processing device 2L includes a frequency classification processing unit 20, a TOI classification processing unit 21, and a TOA classification processing unit 2.
Consists of two. The frequency classification processing unit 20 is a device that classifies a plurality of received pulses received by the radio wave detection device based on the frequency, and classifies all the received pulses constituting the pulse group data 1 for each frequency band of each radio wave emission source. Then, a frequency classification number corresponding to the frequency band is assigned to each pulse data.

[0007] The TOI classification processing section 21 is a device for classifying pulse signals constituting the pulse group data 1 based on the pulse arrival intervals (TOI), and is a main pulse signal transmitted from a single radio wave emission source. It is determined whether or not the pulse signal is transmitted from the main radio wave emission source. TO
The I classification processing unit 21 creates a histogram of the pulse arrival intervals (TOI) from the pulse arrival times (TOA) of the respective pulse signals, and the number of pulse signals having the same pulse arrival interval (TOI) constitutes the pulse group data 1. Of the total number of pulse signals to be obtained. The ratio is compared with a predetermined value. If the ratio is equal to or more than the predetermined value, it is determined that the pulse signal is coming from the same radio wave emitting source, and the pulse arrival interval (TOI) is formed. The same TOI classification number is assigned to the given pulse signal. That is, the pulse arrival interval (T
OI) is statistically processed to extract main pulse signals and assign classification numbers.

[0008] The TOA classification processing section 22 also converts the pulse signals constituting the pulse group data 1 into respective pulse arrival intervals (TOI).

Based on one of the pulse arrival times (TOA), the combination data of the pulse arrival intervals (TOI) is created. Then, it is determined for all the pulse group data 1 whether or not a pulse train is continuously present at each pulse arrival interval (TOI). As a result, if a pulse signal arrives continuously for a predetermined number of times or more at each time corresponding to the pulse arrival interval (TOI), the same TOA classification number is assigned to these pulse signals. That is, a pulse train continuously received at a fixed pulse arrival interval (TOI) is individually searched to extract each pulse signal and assign a classification number.

[0009] In the signal classification processing device 2L of FIG.
The frequency classification processing unit 20 reads the frequency of each pulse signal from the pulse group data 1, converts the frequency data into a classification number for each predetermined frequency band, and assigns a classification number to each pulse data. Then, the frequency classification number assigned to each pulse is written to the pulse group data 1. Upon completion of this classification processing, the frequency classification processing unit 20 outputs a classification processing start instruction to the TOI classification processing unit 21.

[0010] The TOI classification processing section 21 reads out the pulse arrival time (TOA) from the pulse group data 1 for the pulse signals to which the same frequency classification number is assigned by the frequency classification processing section 20. Then, the pulse arrival interval (TO
A histogram of I) is created, a TOI classification number is assigned to a pulse signal that can be determined to have been transmitted from a main radio wave emission source, and written to the pulse group data 1. TO
When this classification processing is completed, the I classification processing unit 21
A classification processing start instruction is output to the A classification processing unit 22.

The TOA classification processing unit 22 generates a pulse signal for a pulse signal that has not been classified by any of the frequency classification processing unit 20 and the TOI classification processing unit 21, that is, a pulse signal to which neither a frequency classification number nor a TOI classification number is assigned. The arrival time (TOA) is read from the pulse group data 1. Then, a combination data of the pulse arrival intervals (TOI) is created, and a TOA classification number is assigned to a pulse signal that can be determined that the pulse train of the pulse arrival intervals is continuously present, and is written into the pulse group data 1. It is. When the classification processing by the TOA classification processing unit 22 ends, all processing by the signal classification processing device 2L ends.

Compared with the signal classification processing device 2L of FIG. 8, it is different in that the signal classification processing device does not have the TOI classification processing unit.

In the signal classification processing device 2N, when a frequency classification number is assigned based on a frequency band by the frequency classification processing unit 20, a classification processing start instruction is output from the frequency classification processing unit 20 to the TOA classification processing unit 22. . The TOA classification processing unit 22 creates combination data of a pulse arrival time (TOA) and a pulse arrival interval (TOI) for pulse signals to which the same frequency classification number is assigned. Then, it is determined whether or not the pulse trains of the pulse arrival interval (TOI) are continuously present.
Is determined.

As a result, the pulse arrival interval (TOI)
When there are consecutive pulse signals, the same TOA classification number is assigned to these pulse signals. TO
The A classification processing section 22 performs the above classification processing on all the frequency classification numbers assigned by the frequency classification processing section 20. Then, when the classification processing by the TOA classification processing unit 22 ends, all the processing by the signal classification processing device ends.
