部分を示す。 FIG. 1 is a system block diagram showing an embodiment of the present invention, FIG. 2 is a diagram for explaining the operation and effect of the present invention, and FIG. 3 is a system block diagram of a conventional multi-target tracking device. In the figure, 1 is a transmitting/receiving antenna, 2 is a transmitting/receiving switch, 3 is a transmitter, 4 is a receiver, 5 is a target detection circuit, 6 is a target manager, 7 is a search pattern forming circuit, 8 is a tracking pattern forming circuit, 9 is a search and tracking pattern control circuit, 10 is a PR
T calculation circuit, a is the time required for searching without a tracking target or with the conventional method, b is the time required for searching with the method of the present invention, c is the time required for tracking, and d is the time required for TF due to tracking occurring in the conventional method. This is the amount of increase. Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

a transmitting and receiving antenna that emits and receives radio waves;
A receiver that receives received waves from this transmitting/receiving antenna, a target detection circuit that detects targets using the received waves received by this receiver, and manages target information newly detected from this target detection circuit. A multifunction device characterized by comprising a target management device, a means for calculating a PRT (pulse repetition period) necessary for a search from target information from the target management device, and a means for forming a search pattern from the PRT. Target tracking device.
