摘要： PURPOSE:To accumulate pulses to equal degrees irrespective of length of coming intervals by providing an accumulation limit detecting circuit per each regulated frequency, pulse width or azimuth and presetting limit on the circuit according to coming frequency of signals. CONSTITUTION:Pulse data (PD) 1 is classified into each regulated frequency range by a frequency classifying circuit 3. When a gate 4 corresponding to the frequency is closed at this time, the PD is not stored in a pulse accumulation memory 2 while when the gate 4 is opened, the PD is stored in the memory 2 and at the same time the number of accumulated pulses in a pulse number counting circuit 6 is incremented by one. Then an accumulation limit detection circuit 8 judges whether or not a number 7 of accumulated pulses has reached a preset maximum accumulated pulse number limit and outputs a gate control signal 9 according to the judgment to the gate 4. When the signal 9 is zero, it means that measurement is to be continued, so that the gate 4 is kept open while when the signal is 1, it means that measurement is complete so that the gate 4 is closed.

摘要： PROBLEM TO BE SOLVED: To make it possible to rapidly identify by evaluating an evaluated value output from evaluated value extracting means at each group according to the order of importance, and identifying a radar output with received radio wave. SOLUTION: An importance radio wave data grouping circuit 17 groups a plurality of data of an identifying table 1 with the different values from respective radio wave generation sources as important data. The grouped data 15 is output as identifying key data 16 via an identifying key data judging circuit 14, ACL distributed by an ACL distributor 3, and output as an identifying table 7. Then, the received radio wave data 8 from the radar wave is collated with the data of the table 7 by a coincidence data ACL value extractor 4. In the case of coincidence, it is output as an ACL value, and also output to the unit NO.9 of a radio wave generation source. The ACL vale of each unit NO.9 is added by an adder 5, and the sum is output as an addition result 11. An identifying candidate extractor 6 outputs the unit NO.9 corresponding to the result 11 as an identification candidate 12.

摘要： PURPOSE:To preserve transfer information in a sender side equipment till a receiver side equipment surely receives the information by providing a reception state discrimination means, an acknowledgement command transmission means and an acknowledgement command discrimination means to the transfer equipment. CONSTITUTION:A 2nd transmitter 2A uses a data normal/abnormal discrimination circuit (reception state discrimination means) 14 to discriminate whether or not the information from a 1st transmitter 1A is normally received. As a result, when it is discriminated that the information from the transmitter 1A is normally received, an acknowledgement command representing it is sent to the transmitter 1A via an acknowledgement setting circuit 20, an acknowledgement setting memory 21 (acknowledgement command transmission means) and a data bus 3. When a received command is an acknowledgement command, an acknowledgement discrimination circuit (acknowledgement command discrimination means) 22 provides an output of an update signal to an RT side CPU 4 of the transmitter 1A.

摘要： PURPOSE:To perform position detection of high accuracy automatically and by real time in a plurality of radars by dividing a map into a mesh(cell) shape, and counting a number of traversing times in each cell where an azimuth line crosses. CONSTITUTION:An intramachine position data 3, output by an azimuth data 1 and a navigation device 2, is input to an azimuth correlative cell detecting circuit 4 and processed as an azimuth vector. In the circuit 4, in the case that a map is divided into a cell of mesh shape, that is, matrix shape, whichever cell this azimuth vector passes or not is detected and output as a cell/memory concerned signal 5. This signal 5 is accumulated for a fixed time while added to a concerned memory in a cell/memory 6 provided in a quantity of the total cells of dividing the map. After the fixed time, a cell/memory concerned count value 7 is fed to a peak detecting circuit 8 from the memory 6. In the circuit 8, the cell of the count value 7 in a fixed value or more is decided in a radar existing position to output a detected position data 9.

摘要： PURPOSE:To securely receive accurate data by deciding whether or not sent data are normal by a 1st system and resending the data to the 1st system by a 2nd system when the data are abnormal. CONSTITUTION:A transmission command/reception command decision circuit 15 decides whether an acknowledgement command transferred to an RT side is a transmission command or reception command. After it is decided that the command is the transmission command, an acknowledgement decision circuit 20 decides the acknowledgement command. An acknowledgement control circuit 21 transfers the result data from a reception command data normal/abnormal result storage memory 19 from RT to BC. Then the BC side receives the result data from the RT and sets the data in an in-BC data setting memory 14, and it is confirmed whether the result data are normal or abnormal. When the data are abnormal, the same reception command and the same data set in a command setting memory 13 are sent again from the BC to the RT.

摘要： PURPOSE:To detect an in-pulse frequency mode in real time at the time of one-pulse measurement by providing a multiplier for spectrum width and pulse width outputted by a compressive receiving and a pulse width measuring circuit and a comparator which decides whether or not the output of the multiplier is larger than a constant value. CONSTITUTION:The subject circuit consists of the compressive receiving circuit 2 which outputs the spectrum width 4 with an input signal 1, the pulse width measuring circuit 3 which outputs the pulse width 5 similarly, the multiplier 6 for both their outputs, the comparator 7 which compares its output with the constant value, etc. Then the signal 1 passes through the circuits 2 and 3 to obtain the spectrum width 4 and pulse width 5, which are supplied to the multiplier 6 and comparator 7 to obtain a status 8 indicating whether or not the input signal is a frequency chirp signal. The comparator 7 outputs the status 8 which is '1' indicating the chirp signal when the output of the multiplier 6 is larger that the constant value, but '0' indicating a fixed signal when the output of the multiplier is nearly equal. Consequently, the in-pulse frequency mode can be detected in one-pulse measurement.
