RAMで構成されている。FIG. 1 is a block diagram of a signal recording/reproducing apparatus according to an embodiment of the present invention. When recording, a received video signal from the receiver of the radar device is input to the interface section 2 through the input terminal 11. In the interface section 2, the received video signal is sampled in terms of time and amplitude to become a digital signal and sent to the next-stage pre-switching section 3. The front switching section 3 selects only the digital signals in the set area (distance, direction, transmission beam number) according to the switching control signal from the control section 1, and selects only the digital signals of the set area (distance, direction, transmission beam number), and stores the memory section of the designated system from the control section 1. 4. The memory section 4 is composed of a RAM having a storage capacity of one track of the magnetic disk medium used in the storage section 6.

媒体上に記録される。The memory section 4 has two systems. When one system is writing a digital signal whose area is set according to the timing of the radar device, the other system is writing the digital signal at a timing faster than the timing of the radar device. The signal is read out and sent to the rear switching section 5 at the next stage. The rear switching section 5 selects the outputs of the two memory sections 4 according to the switching control signal from the control section 1 and sends the selected outputs to the storage section 6 . In the storage section 6, the digital signal from the rear switching section 5 is recorded on each track of the magnetic disk medium, and when one track is completed, the magnetic head changes the track according to the control signal from the control section 1. This track changing operation is controlled so as to end before reading of the next digital signal from the memory section 4 begins. Area setting values are also recorded on the magnetic disk medium because they are necessary during reproduction.

信号等を発生する。Reproduction is performed in the reverse procedure to the above-mentioned recording, and the digital signal from the storage section 6 is sent to the memory section 4 through the rear switching section 5, and the digital signal is sent from the front switching section 3 in accordance with the timing of the radar device. The signal is sent to the interface section 2 as a digital signal, converted into an analog signal, and outputted from the output terminal 12 as a reproduced video signal. When performing repeated reproduction, the movement of the magnetic head of the storage section 6 is controlled by the control section 1;
You can move to the initial track in a short time. The control unit 1 is composed of a memory circuit, an area determination circuit, and a timing generation circuit. The memory circuit is used to store area setting values during recording and playback, and the area determination circuit is used to store the set area (distance, direction, etc.). , transmission beam number) and the performance of the magnetic disk drive, determines whether real-time recording is possible, and if real-time recording is possible, sends an area setting signal to the timing generation circuit to start real-time recording. If there is a setting that is impossible to record, a correction request signal is sent. The timing generation circuit receives external synchronization trigger signals, azimuth signals, transmission beam number signals, etc., and generates synchronization signals, control signals, etc. necessary for each component of the signal recording and reproducing device according to signals from the area determination circuit.
