摘要： PURPOSE:To prevent a target malrecognition rate from increasing by rotating two radar scanners simultaneously so that they are shifted by 180 deg. out of rotary phase and displaying the images of the radar scanners in the respective areas of a display screen at the same time. CONSTITUTION:The 1st and the 2nd radar scanners 1 and 2 equipped with motors 3 and 4 and the 1st and the 2nd transmitter receivers 5 and 6 are arranged closely to each other and also so constituted that they rotate having a 180 deg. rotary phase shift. Analog signals from both transmitter receivers 5 and 6 are converted into digital signals, which are mixed together to display simultaneously images based upon both received signals in areas S1 and S2 obtained by dividing the circular display screen S equally into two. When both radar scanners 1 and 2 rotate while shifting by 180 deg. out of rotary phase from each other, the images based upon both received signals are displayed in the areas S1 and S2 and one radar image is displayed on the screen S. Consequently, the radar image is updated without any decrease in the number of pulse bits per one turn of the radar scanners.

摘要： PURPOSE:To easily check and correct the destruction and falsification of data on a data base by reading out the same data after increasing the number of accesses within the ranges of 1st-3rd data bases out of the signal contents of the deciding results obtained from a class deciding means in response to general, medium and advanced classes respectively. CONSTITUTION:In case an ID code is inputted from a card reader 32 only, a general operator is discriminated and the data on a 1st data base is read out. When an ID code and a password are inputted from the reader 32 and a password input equipment 33 respectively, a medium operator is discriminated and the data on the 1st and 2nd data bases are read out. When an ID code, a password and an answer signal are inputted fro the reader 32, the input equipment 33 and a transmitter/receiver 34 respectively, an advanced operator is discriminated and the data on the 1st-3rd data bases are read out. In such a way, the advanced operator can easily detect the destruction of the data on the data base with reference to the 1st-3rd data bases 42-44 via the advance operator even though the general operator destroys said data.

摘要： PURPOSE:To make it possible to avoid danger during navigation, by instantaneously opening the channel with a specific ship of which ship name is also unclear among a large number of ships to perform the exchange of informations. CONSTITUTION:Each of ships A, B has a coder 5 storing a code specifying its own ship. A question transmitter 1 using a directional antenna 30 performs a general calling toward the direction of a ship desired to communicate and sends its own inherent code. This signal is received by each ship in a transmitting direction and each receiving ship transmits its own inherent code toward the transmitting ship from a response transmitter 3 and an antenna 50. The transmitting ship side uses the time gate corresponding to the distance from the destination ship to selectively extract only the response signal of the partner ship and knows the inherent code thereof. Thereafter, this inherent code is used to perform mutual communication to open the channel between both ships.
