摘要:
A navigation device (1) is provided, which may include an acquiring module (31) and a route creating module (32). The acquiring module (31) may acquire at least a departing location, a destination location and nautical chart information to be used for creating a traveling route for a ship. When a given navigable area is divided into a first navigable area and a second navigable area based on a given condition, the route creating module (32) may create a route being shorter in total distance and taking priority in passing the first navigable area than the second navigable area, based on the departing location, the destination location, and the nautical chart information.
摘要:
A Continuous Transmission Frequency Modulated (CTFM) detection apparatus is provided. The CTFM detection apparatus includes a projector (2), a receiving element (31a, 31b), a motion mechanism (4), and a target object information generator (18). The projector (2) is configured to transmit a frequency modulated transmission wave and to generate a 3-dimensional transmission beam. The receiving element (31a, 31b) is configured to receive a reflected wave, the reflected wave comprising a reflection of the transmission wave. The motion mechanism (4) is configured to set the receiving element (31a, 31b) in motion and to make a reception beam formed by the receiving element (31a, 31b) scan a 3-dimensional space within the transmission beam. The target object information generator (18) is configured to generate information on target objects within the 3-dimensional space based at least in part on a beat signal generated based at least in part on the transmission wave transmitted by the projector (2) and the reflected wave received by the receiving element (31a, 31b).
摘要:
This disclosure provides a target length measuring apparatus (1), which includes a transceiver (10,20,30) for transmitting a detection wave signal and receiving an echo signal, a kind identifier (40) for detecting a target object and identifying a kind of the target object, based on the echo signal received by the transceiver (10,20,30), a measuring unit (51) for measuring a target strength of the target object based on the echo signal received by the transceiver (10,20,30), a memory (53) for storing a standardized value of the target strength for each kind of the target object, and a calculator (52) for calculating a target length of the target object using the standardized value of the target strength stored in the memory (53) and the target strength of the target object measured by the measuring unit (51), for each kind of the target object identified by the kind identifier (40).
