  FIG. 1A is a diagram for explaining the first embodiment. Reference numerals 101a to 101g are UWB nodes placed in areas where military forces are expected to be deployed. Among them, UWB nodes 101f and 101g receive GPS signals. Equipped with a machine, these will be the standard UWB nodes. A soldier 102 deployed in the area carries a UWB node. Reference numeral 103 denotes a vehicle deployed in the area, represented by a tank, and a passenger carries a UWB node. Reference numeral 104 denotes a helicopter, and 105 denotes a monitoring unit.

  UWB nodes 101a-101g are scattered by helicopter 104 and placed in an area where forces are expected to be deployed. The reference UWB nodes 101f and 101g measure the position on the earth using a GPS receiver. The monitoring unit 105 is installed apart from the area where the UWB nodes 101a to 101g are scattered. A UWB signal communicates using a pulse having a very short time width of several ns to several tens ns. Information is communicated at the timing of sending this pulse. Each UWB node 101a (-101g) transmits its own identification signal and transmission time. Each UWB node (101a, 101b) (101b) receives an identification signal from another node and a transmission time at a time according to the distance between the transmission node and the reception node. Each UWB node 101 a to 101 g sends the identification signal, the transmission time, and the reception time received from other nodes to the monitoring unit 105. At this time, the reference UWB nodes 101 f and 101 g also send the position on the earth where the measured self is placed to the monitoring unit 105. The monitoring unit 105 constitutes a relative position analysis unit 1051 with a computer, and the relative position analysis unit 1051 analyzes the data signal regarding the distance sent from each UWB node 101a to 101g to grasp the relative positional relationship. By using UWB, the relative position between nodes can be grasped in units of several cm. Further, the monitoring unit 105 is configured by an absolute position calculation unit 1052 with a computer, and the UWB nodes 101a to 101g monitored by the monitoring unit 105 on the earth according to the positions on the earth measured by the reference UWB nodes 101f and 101g. The absolute position calculation unit 1052 calculates the position.

  After the position of each UWB node 101a to 101g on the earth is grasped, when the soldier 102 or the vehicle 103 carrying the UWB node approaches one of the UWB nodes 101a to 101g, the UWB carried by the soldier 102 or the vehicle 103 is carried out. The identification signal transmitted by the node and the transmission time are received by the nearby UWB node 101a (to or 101g). The distance between the soldier 102 or the vehicle 103 and the received UWB nodes 101a to 101g is measured by the received node according to the transmission time. The received identification number information and distance measurement information are sent to the monitoring unit 105 and sequentially recorded in the soldier and vehicle identification number recording unit 1053. As the soldier 102 and the vehicle 103 move, the UWB nodes 101a to 101g grasp their positions and identification numbers and add them to the identification number recording unit 1053 in time series. Information on the deployment status of the troops input is obtained from the information stored in the identification number recording unit 1053. The number of troops can be easily ascertained when an airborne unit or the like is withdrawn, and when using an identification number, it can be easily grasped whether or not the person has withdrawn. In addition, by placing a UWB node on a high-firing gun as a moving node and transmitting an identification signal and transmission time specific to that high-firing gun in the same manner as described above, the position can be grasped, and the position of the thermal power deployment can be grasped. , Deployment adjustment becomes easy.

  FIG. 1B is a diagram for explaining the second embodiment. 101h to 101n are UWB nodes placed in an area where enemy forces are expected to be added. Among them, UWB nodes 101m and 101n are connected to GPS. Equipped with receivers, these are the reference UWB nodes. 1102 is an enemy soldier deployed in the area, 1103 is an enemy vehicle deployed in the area, 1104 is a helicopter, and 1105 is a monitoring unit.

  UWB nodes 101h-101n are scattered by helicopter 1104 and placed in an area where enemy forces are expected to develop. The reference UWB nodes 101m and 101n measure the position on the earth using a GPS receiver. The monitoring unit 1105 is installed apart from the area where the UWB nodes 101h to 101n are scattered. The UWB signal communicates using a pulse with a very short time width of 1 ns or less. Information is communicated at the timing of sending this pulse. Each UWB node 101h (-101n) transmits its own identification signal and transmission time. Each UWB node (101h,) 101i (101n) receives an identification signal from another node and a transmission time at a time according to the distance from the transmission node reception node. Each of the UWB nodes 101 h to 101 n sends the identification signal, the transmission time, and the reception time received from other nodes to the monitoring unit 1105. At this time, the reference UWB nodes 101m and 101n also send the position on the earth where the measured self is placed to the monitoring unit 1105. The monitoring unit 1105 configures a relative position analysis unit 11051 with a computer, and the relative position analysis unit 11051 performs data analysis on the data signals transmitted from the UWB nodes 101h to 101n to grasp the relative positional relationship. By using UWB, the relative position between nodes can be grasped in units of several cm. Further, the monitoring unit 1105 constitutes an absolute position calculation unit 11052 with a computer, and the UWB nodes 101h to 101n monitored by the monitoring unit 1105 are detected on the earth according to the positions on the earth measured by the reference UWB nodes 101m and 101n. Is calculated by the absolute position calculation unit 11052.

  The UWB nodes 101h to 101n emit pulses at a predetermined cycle while the positions of the UWB nodes 101h to 101n on the earth are known. When the enemy soldier 1102 or the vehicle 1103 approaches the UWB node 101h, for example, the pulse signal emitted from the node is reflected by the enemy soldier 1102 or the enemy vehicle 1103, and the pulse that is the reflected wave is received by the UWB node 101h. . The UWB node 101h that emits and receives the pulse measures the distance between the soldier 1102 or the vehicle 1103 based on the time when the pulse is emitted and the time when the pulse is received. The distance measurement information and the identification signal of the UWB node 101h are sent to the identification number recording unit 11053 of the monitoring unit 1105, and the distance measurement information is recorded corresponding to the identification number. By this record, the UWB node 101h having the identification number knows the presence of enemy soldiers in the vicinity of the UWB node 101h and the distance to the enemy soldier, and determines the movement of the soldier based on the change in the distance sent. When two or more UWB nodes recognize the presence of an enemy soldier, whether the distance measured by the two or more UWB nodes is determined as the distance from the same soldier or not, whether it is the same soldier or not Decide whether or not. Further, when there are a large number of enemy soldiers 1102 and enemy vehicles 1103, the pulses from the UWB nodes 101h to 101n are reflected from the enemy soldiers 1102 and vehicles 1103, reflected from many objects like irregular reflections, and reflected. Waves are received, and distances measured by these received waves are sent to the monitoring unit 1105 together with identification signals by the UWB nodes 101h to 101n. The monitoring unit 1105 configures an object identification analysis unit 11054 with a computer, analyzes signals of distance information sent from the respective UWB nodes 101h to 101n, distinguishes between a person and a vehicle, and identifies a vehicle type by a statistical method. , Grasp the number of enemies, grasp the movement situation, etc.

In remote attack means such as cannons and missiles, altitude information is a major factor in the accuracy of hitting as well as plane information of longitude and latitude. Usually, it is easy to obtain altitude information of allies, but enemy altitude information has only to be calculated by identifying the enemy position (latitude, longitude) from a helicopter or the like and comparing it with map information.
FIG. 2 is a diagram for explaining the third embodiment, in which 205 is a monitoring unit and 2055 is a movement vector calculation means. The monitoring unit 205 includes the same relative position analysis unit 2051, absolute position calculation unit 2052, identification number recording unit 2053, and object identification analysis unit 2054 as described in the first and second examples, and further moves Vector calculation means 2055 is provided. The other symbols are the same as those used in FIGS. 1 (a) and 1 (b).
The movement vector calculation means 2055 includes a friend grasped as described in the first embodiment by the soldier deployment information system configured by the relative position analysis unit 2051, the absolute position calculation unit 2052, and the identification number recording unit 2053, and further the relative position analysis unit 2051. From the position information of the enemy's longitude, latitude, and altitude as described in the second embodiment by the enemy position grasping system constituted by the absolute position calculating unit 2052, the identification number recording unit 2053, and the object identification analyzing unit 2054, the position information Time variation and speed information are obtained, and movement vector information for each enemy and ally is calculated based on this speed information. A remote attack means (not shown) is used as an indicator of a remote attack such as a gun or a missile based on the movement vector information.

  It is possible to accurately grasp the positional relationship of the points where the UWB nodes are scattered by using a GPS receiver, analyze the received signal from the moving node with a computer, or analyze the received reflected wave with a computer, The movement of the node and the object can be grasped.
