    摘要： A parameter changer (116) changes the parameter of the complementary code input from a multiplexer (102). A separator (117) separates the time-multiplexed complementary code of which parameter has been changed into the code sequences at the even numbers of the time slots and the code sequences at the odd numbers of the time slots. A demodulator (118) demodulates the received signals using the parameter-changed complementary code in order to obtain the demodulated signal. An interference identifying unit (122) identifies the interference signal included in the received signals using the demodulated signal from the demodulator (118).

    摘要： A wide monitor area can be covered by switching the connection between a plurality of sensors (102-1∼102-m, A1∼A4, 601∼605) and a transmission/reception device (101, 200, 209, 210) using a switch device (103, 201, 202, 606) of a target detection apparatus in a time division manner. When only two target detection apparatuses (S 1 , S 2 ) are used in positioning a target, the position of a target can be identified according to the information about an area (402) common to both angle ranges (SR 11 , SR 12 , SR 13 , SR 21 , SR 22 , SR 23 ) covered by the two apparatuses or the total propagation distance information from one apparatus to the other apparatus through each target.
