Description

この発明は、高周波信号出力装置、該高周波信号出力装置に用いられる信号出力方法及び信号出力制御プログラムに係り、特に、高周波のバースト状のパルスが繰り返される高周波信号を１ヒット目から安定して外部へ送出する場合に用いて好適な高周波信号出力装置、該高周波信号出力装置に用いられる信号出力方法及び信号出力制御プログラムに関する。   The present invention relates to a high-frequency signal output device, a signal output method used for the high-frequency signal output device, and a signal output control program, and in particular, a high-frequency signal in which a high-frequency burst pulse is repeated is stably output from the first hit. The present invention relates to a high-frequency signal output device suitable for use when transmitting to a signal, a signal output method used in the high-frequency signal output device, and a signal output control program.

高周波信号出力装置により、高周波のバースト状のパルスが繰り返される高周波信号を発生する場合、電源投入直後や動作開始直後では、高周波信号の波形が不安定となり、安定した正規の波形の信号が出力されるまでに数ヒット分の時間が必要となる。この現象は、高周波信号出力装置を構成する高周波信号発生部の内部で、出力電力を監視して高速で規定値に設定するためのフィードバック制御機能が作動することにより発生し、高周波信号の出力を安定して維持するために必然的なものである。   When the high-frequency signal output device generates a high-frequency signal in which high-frequency burst-like pulses are repeated, the waveform of the high-frequency signal becomes unstable immediately after the power is turned on or immediately after the operation is started, and a stable regular waveform signal is output. It takes several hits to complete. This phenomenon occurs when the feedback control function for monitoring the output power and setting it to the specified value at high speed is activated inside the high-frequency signal generator constituting the high-frequency signal output device. It is inevitable to keep stable.

この種の高周波信号出力装置は、たとえば図３に示すように、高周波信号発生部１と、パルス発生部２と、制御部３とから構成されている。
この高周波信号出力装置では、図４に示すように、制御部３により、動作開始制御信号ｃａが高周波信号発生部１に与えられると共にパルス制御信号ｃｂがパルス発生部２に与えられる。パルス発生部２により、パルス制御信号ｃｂに基づいて、高周波信号発生部１に対して同期信号ｓａが送出されてパルス繰返し周波数が設定され、また、同期信号ｓａに同期した駆動パルスｄｐが出力される。 For example, as shown in FIG. 3, this type of high-frequency signal output device includes a high-frequency signal generator 1, a pulse generator 2, and a controller 3.
In this high frequency signal output device, as shown in FIG. 4, an operation start control signal ca is supplied to the high frequency signal generator 1 and a pulse control signal cb is supplied to the pulse generator 2 by the controller 3. Based on the pulse control signal cb, the pulse generator 2 sends a synchronization signal sa to the high-frequency signal generator 1 to set a pulse repetition frequency, and outputs a drive pulse dp synchronized with the synchronization signal sa. The

高周波信号発生部１により、高周波信号ｓｈが発生する。この高周波信号ｓｈは、動作開始制御信号ｃａが高周波信号発生部１に与えられた直後では、波形が不安定となり、安定した正規の波形の信号が出力されるまでに３ヒット分の時間が必要となる。この高周波信号ｓｈでは、４ヒット目から安定した正規の波形となり、制御部３により設定された周波数、パルス幅及び出力レベルを有するバースト状のパルスが発生するバースト期間と同パルスが発生しない非バースト期間とが、パルス発生部２により設定されたパルス繰返し周波数で交互に繰り返される。この高周波信号ｓｈでは、たとえば、周波数ｆが３ＧＨｚ、パルス幅τが１００μｓ、出力レベルが＋１ｄＢｍ、及びパルス繰返し周波数ＰＲＦ（Pulse Repetition Frequency）が１０００ｐｐｓ（pulse per second）（周期；１ｍｓ）に設定されている。パルス発生部２から出力される駆動パルスｄｐは、高周波信号発生部１から出力される高周波信号ｓｈをタイミング的に同期して入力する増幅回路などに使用される。   The high frequency signal generator 1 generates a high frequency signal sh. The high-frequency signal sh is unstable in waveform immediately after the operation start control signal ca is given to the high-frequency signal generator 1, and a time of 3 hits is required until a stable regular waveform signal is output. It becomes. This high-frequency signal sh has a stable regular waveform from the fourth hit, and a non-burst in which the same pulse is not generated as a burst period in which a burst-like pulse having the frequency, pulse width, and output level set by the control unit 3 is generated. The period is alternately repeated at the pulse repetition frequency set by the pulse generator 2. In this high-frequency signal sh, for example, the frequency f is set to 3 GHz, the pulse width τ is set to 100 μs, the output level is set to +1 dBm, and the pulse repetition frequency PRF (Pulse Repetition Frequency) is set to 1000 pps (pulse per second) (cycle: 1 ms). Yes. The drive pulse dp output from the pulse generator 2 is used in an amplifier circuit that inputs the high-frequency signal sh output from the high-frequency signal generator 1 in synchronization with the timing.

上記の高周波信号出力装置の他、この種の関連技術としては、たとえば、特許文献１に記載された自動終端切替装置がある。
この自動終端切替装置では、電圧発生部により高周波伝送線に印加される直流電圧が電圧検出部で検知されて伝送路切替部が制御されることで、入力端子から入力される高周波信号が終端抵抗で終端されるか、又は高周波出力端子へ伝送されるかが自動で切り替えられる。これにより、高周波伝送線における終端処理に際して、人為的なメインテナンスが必要なく、高周波特性の向上及び小型軽量化を図ることができる。 In addition to the above-described high-frequency signal output device, this type of related technology includes, for example, an automatic termination switching device described in Patent Document 1.
In this automatic termination switching device, a DC voltage applied to the high-frequency transmission line by the voltage generation unit is detected by the voltage detection unit and the transmission line switching unit is controlled, so that the high-frequency signal input from the input terminal Is terminated automatically or transmitted to the high frequency output terminal. As a result, no artificial maintenance is required for the termination process in the high-frequency transmission line, and the high-frequency characteristics can be improved and the size and weight can be reduced.

実施形態Embodiment

図１は、この発明の一実施形態である高周波信号出力装置の要部の電気的構成を示すブロック図である。
この形態の高周波信号出力装置は、同図に示すように、高周波信号発生部１１と、パルス発生部１２と、制御部１３と、高周波出力制御部１４とから構成されている。高周波信号発生部１１は、高周波信号ｓｈを発生し、同高周波信号ｓｈでは、設定された周波数、パルス幅及び出力レベルを有するバースト状のパルスが発生するバースト期間と同パルスが発生しない非バースト期間とが、設定されたパルス繰返し周波数で交互に繰り返される。パルス発生部１２は、制御部１３から与えられたパルス制御信号ｃｂに基づいて、高周波信号発生部１１に対して同期信号ｓａを送出することにより、上記パルス繰返し周波数を設定する。また、パルス発生部１２は、同期信号ｓａに同期した駆動パルスｄｐを出力する。 FIG. 1 is a block diagram showing an electrical configuration of a main part of a high-frequency signal output device according to an embodiment of the present invention.
As shown in the figure, the high-frequency signal output device of this embodiment includes a high-frequency signal generator 11, a pulse generator 12, a controller 13, and a high-frequency output controller 14. The high-frequency signal generator 11 generates a high-frequency signal sh. In the high-frequency signal sh, a burst period in which a burst-like pulse having a set frequency, pulse width, and output level is generated, and a non-burst period in which the same pulse is not generated. Are alternately repeated at the set pulse repetition frequency. The pulse generation unit 12 sets the pulse repetition frequency by sending a synchronization signal sa to the high frequency signal generation unit 11 based on the pulse control signal cb given from the control unit 13. The pulse generator 12 outputs a drive pulse dp that is synchronized with the synchronization signal sa.

制御部１３は、信号出力制御プログラムに基づいて動作するコンピュータで構成され、高周波信号発生部１１に対して、高周波信号ｓｈの周波数、パルス幅及び出力レベルを設定する。また、制御部１３は、動作開始制御信号ｃａを高周波信号発生部１１へ与えると共にパルス制御信号ｃｂをパルス発生部１２へ与え、かつ、上記動作開始制御信号ｃａを与えてから所定時間が経過するまで駆動信号ｄａをノンアクティブモードとする一方、動作開始制御信号ｃａを与えてから上記所定時間が経過した後、アクティブモードの駆動信号ｄａを高周波出力制御部１４へ与える。上記所定時間は、特に、この実施形態では、高周波信号発生部１１に動作開始制御信号ｃａを与えてから高周波信号ｓｈのパルスが正規の波形になるまでの時間が実験などであらかじめ測定され、この時間以上に設定されている。   The control unit 13 is configured by a computer that operates based on a signal output control program, and sets the frequency, pulse width, and output level of the high-frequency signal sh to the high-frequency signal generation unit 11. In addition, the control unit 13 provides the operation start control signal ca to the high frequency signal generation unit 11 and also provides the pulse control signal cb to the pulse generation unit 12, and a predetermined time elapses after the operation start control signal ca is provided. The drive signal da is set to the non-active mode until the operation start control signal ca is given, and then the active mode drive signal da is supplied to the high-frequency output control unit 14 after the predetermined time has elapsed. In particular, in this embodiment, the predetermined time is measured in advance by an experiment or the like until the pulse of the high-frequency signal sh becomes a normal waveform after the operation start control signal ca is given to the high-frequency signal generator 11. It is set over time.

高周波出力制御部１４は、駆動信号ｄａがノンアクティブモードのとき、高周波信号発生部１１から出力されている高周波信号ｓｈを終端する一方、同駆動信号ｄａがアクティブモードのとき、高周波信号ｓｈを出力する図示しない切替え手段と、同切替え手段から出力される高周波信号ｓｈを同期信号ｓｂに同期して高周波信号ｓｊとして外部へ送出する図示しないフリップフロップとから構成されている。パルス発生部１２から出力される駆動パルスｄｐは、高周波出力制御部１４から出力される高周波信号ｓｊをタイミング的に同期して入力する増幅回路などに使用される。   The high frequency output control unit 14 terminates the high frequency signal sh output from the high frequency signal generation unit 11 when the drive signal da is in the non-active mode, and outputs the high frequency signal sh when the drive signal da is in the active mode.

図２は、図１の高周波信号出力装置の動作を説明するタイムチャートである。
この図を参照して、この形態の高周波信号出力装置に用いられる信号出力方法の処理内容について説明する。
この高周波信号出力装置では、図２に示すように、制御部１３により、動作開始制御信号ｃａが高周波信号発生部１１に与えられると共にパルス制御信号ｃｂがパルス発生部１２に与えられる。高周波信号発生部１１により、高周波信号ｓｈが発生する。この高周波信号ｓｈは、動作開始制御信号ｃａが高周波信号発生部１１に与えられた直後では、波形が不安定となり、安定した正規の波形の信号が出力されるまでに３ヒット分の時間が必要となる。この高周波信号ｓｈでは、４ヒット目から安定した正規の波形となり、制御部１３により設定された周波数、パルス幅及び出力レベルを有するバースト状のパルスが発生するバースト期間と同パルスが発生しない非バースト期間とが、パルス発生部２により設定されたパルス繰返し周波数で交互に繰り返される（高周波信号発生処理）。この高周波信号ｓｈは、たとえば、周波数ｆが３ＧＨｚ、パルス幅τが１００μｓ、出力レベルが＋１ｄＢｍ、及びパルス繰返し周波数ＰＲＦ（Pulse Repetition Frequency）が１０００ｐｐｓ（pulse per second）（周期；１ｍｓ）に設定されている。 FIG. 2 is a time chart for explaining the operation of the high-frequency signal output device of FIG.
With reference to this figure, the processing content of the signal output method used for the high frequency signal output device of this form is demonstrated.
In this high frequency signal output device, as shown in FIG. 2, the operation start control signal ca is supplied to the high frequency signal generator 11 and the pulse control signal cb is supplied to the pulse generator 12 by the controller 13. The high frequency signal generator 11 generates a high frequency signal sh. The high-frequency signal sh becomes unstable immediately after the operation start control signal ca is given to the high-frequency signal generator 11, and a time of 3 hits is required until a stable normal waveform signal is output. It becomes. This high-frequency signal sh has a stable regular waveform from the fourth hit, and a non-burst in which the same pulse is not generated as a burst period in which a burst-like pulse having the frequency, pulse width and output level set by the control unit 13 is generated. The periods are alternately repeated at the pulse repetition frequency set by the pulse generator 2 (high frequency signal generation processing). The high-frequency signal sh has, for example, a frequency f of 3 GHz, a pulse width τ of 100 μs, an output level of +1 dBm, and a pulse repetition frequency PRF (Pulse Repetition Frequency) of 1000 pps (pulse per second) (period: 1 ms). Yes.

高周波出力制御部１４では、制御部１３から高周波信号発生部１１に動作開始制御信号ｃａが与えられてから所定時間（すなわち、安定した正規の波形の信号が出力されるまでの３ヒット分の時間）が経過するまで、高周波信号発生部１１の出力側が終端される一方、同所定時間が経過した後、高周波信号発生部１１から出力されている高周波信号ｓｈのパルスが１ヒット目から高周波信号ｓｊとして外部へ送出される（出力制御処理）。   In the high frequency output control unit 14, a predetermined time (that is, a time corresponding to three hits until a signal having a stable normal waveform is output after the operation start control signal ca is given from the control unit 13 to the high frequency signal generation unit 11) The output side of the high-frequency signal generating unit 11 is terminated until the high-frequency signal generating unit 11 ends, and after the predetermined time has elapsed, the pulse of the high-frequency signal sh output from the high-frequency signal generating unit 11 starts from the first hit. To the outside (output control processing).

上記出力制御処理では、制御部１３により、動作開始制御信号ｃａが高周波信号発生部１１に与えられると共にパルス制御信号ｃｂがパルス発生部１２に与えられ、かつ、同動作開始制御信号ｃａが与えられてから所定時間が経過するまで駆動信号ｄａがノンアクティブモード（たとえば、低レベル）とされる一方、同動作開始制御信号ｃａが与えられてから同所定時間が経過した後、アクティブモード（たとえば、高レベル）の駆動信号ｄａが高周波出力制御部１４に与えられる。また、パルス発生部１２により、制御部１３から与えられたパルス制御信号ｃｂに基づいて、高周波信号発生部１１に対して同期信号ｓａが送出されてパルス繰返し周波数が設定され（パルス発生処理）、また、同期信号ｓａに同期した駆動パルスｄｐが出力される。そして、駆動信号ｄａがノンアクティブモードのとき、高周波出力制御部１４により、高周波信号発生部１１から出力されている高周波信号ｓｈが終端される一方、駆動信号ｄａがアクティブモードのとき、同高周波出力制御部１４により、同高周波信号ｓｈが、上記パルス繰返し周波数を有する同期信号ｓｂに同期して高周波信号ｓｊとして外部へ送出される（高周波出力制御処理）。   In the output control process, the control unit 13 provides the operation start control signal ca to the high-frequency signal generation unit 11, the pulse control signal cb to the pulse generation unit 12, and the operation start control signal ca. The drive signal da is set to a non-active mode (for example, a low level) until a predetermined time elapses after that, and after the predetermined time has elapsed since the operation start control signal ca is applied, A high level drive signal da is supplied to the high-frequency output controller 14. Further, the pulse generator 12 sends a synchronization signal sa to the high frequency signal generator 11 based on the pulse control signal cb given from the controller 13, and sets the pulse repetition frequency (pulse generation processing). In addition, a drive pulse dp synchronized with the synchronization signal sa is output. When the drive signal da is in the non-active mode, the high-frequency output controller 14 terminates the high-frequency signal sh output from the high-frequency signal generator 11, while when the drive signal da is in the active mode, the same high-frequency output. The control unit 14 sends out the high frequency signal sh to the outside as a high frequency signal sj in synchronization with the synchronization signal sb having the pulse repetition frequency (high frequency output control processing).

上記高周波出力制御処理では、切替え手段により、駆動信号ｄａがノンアクティブモードのとき、高周波信号発生部１１から出力されている高周波信号ｓｈが終端される一方、駆動信号ｄａがアクティブモードのとき、高周波信号ｓｈが出力される（切替え処理）。フリップフロップにより、上記切替え手段から出力される高周波信号ｓｈが同期信号ｓｂに同期して高周波信号ｓｊとして外部へ送出される（信号送出処理）。   In the high frequency output control process, when the drive signal da is in the non-active mode, the high frequency signal sh output from the high frequency signal generator 11 is terminated by the switching means, while when the drive signal da is in the active mode, the high frequency output control process is performed.
