Abstract

PURPOSE:To reduce considerably the processing quantity of a post-processing concerning the variance of a detection signal, by collecting pulse data and detecting feature data such as maximum, minimum, and smoothed values of various parameter of respective pulses such as pulse intervals, pulse widths, frequencies, and pulse amplitudes. CONSTITUTION:When pulse data 2a passes through a pulse filter 3, the difference between the arrival time of the preceding passing pulse and the arrival time of the current passing pulse is calculated in a circuit 7 of a pre-processing device 12 for detection of the variance of a detection signal, and this difference, namely, a pulse repeat interval is inputted to a register 8 and is stored temporarily. The pulse interval between the current passing pulse and the preceding passing pulse is checked for validity; and if it is valid, a feature detecting circuit 9 calculates a smoothed value of a pulse interval PI and stores it in a feature data storage memory 10. Next, the feature detecting circuit 9 compares the value of the pulse repeat interval with maximum PI data of the feature data memory 10 to renew contents of the memory 10. Thus, the variance of the detection signal is detected beforehand to discriminate whether the analysis of collected data is required or not before the puse analysis on a basis of check results of only feature data, and therefore, the burden of the post-processing is reduced.

Then, in step B6), the JXP1X-
1 data Pn is also compared with the f-pass repetition interval value PIi in the same way as the maximum PI data PIm, and if the noiseless repetition interval value Pit is less than the minimum PI data P1min, the minimum PI data PImin in the memory ae is updated, Otherwise, the minimum PI data of memory cry PIm
The value of in is saved until that time. In this way, the feature detection circuit (9) counts the number of arriving pulses, and calculates the maximum PI,
It calculates the smooth PI and minimum PI, updates the data in the memory aI as appropriate, and waits for the arrival of the next data. and,
In the same way as above, the present feature detection circuit (9) also performs feature detection regarding pulse width, frequency, and pulse amplitude, and the pulse feature data a9 obtained in this way by the feature detection circuit (9) is of the detection signal. This pulse characteristic data αυ is stored in the characteristic data storage memory α.
[After being stored once in the detection signal change detection preprocessing device a
Similarly to pulse data (6), it is output to a connected device (not shown) for post-processing. - As described above, according to the present invention, pulse data is collected, and the maximum, minimum, smoothed value, etc. of the specifications of each pulse such as pulse number and pulse interval, pulse width, frequency, and pulse amplitude are collected. Since the configuration is configured to detect feature data, it is possible to detect changes in the detection signal by simply determining the difference in the value of the feature data without analyzing the pulse data in post-processing. The detailed analysis of the pulse data in step 2 only needs to be performed when a change in the feature data is detected, which has the effect of greatly reducing the amount of post-processing related to changes in the detection signal.

In addition, if the maximum pulse interval and minimum pulse interval, which are characteristic data of pulse intervals, are integer multiples, it can be determined that the detection signal is almost a single signal. This can be reflected in the specifications, which also has the effect of reducing analysis processing time.

(1) A pulse specification calculation circuit that calculates pulse specifications including pulse intervals for incoming pulses and outputs the calculated specifications as pulse data; A pulse filter that passes only those whose intervals fall within a predetermined range, a pulse storage control circuit to which the output pulse data of the pulse filter and filter are stored, and the pulse data is stored in an address 4 controlled by the pulse storage control circuit. Equipped with pulse specification memory,
a pulse repetition interval detection circuit that detects a pulse repetition interval of output pulse data of the pulse filter by directing the incoming pulse to a pulse data collection device that collects pulse data having pulse specifications within a predetermined range; and a feature data storage memory that stores the feature data, and a detection signal change detection pre-processing device that detects a change in the detection signal in advance. Characteristic pulse data acquisition device. .
