摘要： PROBLEM TO BE SOLVED: To provide a device for signal processing which prevents echo of a target from being weakened by scan correlation.SOLUTION: A signal processing part 17 adjusts a level of echo signal after scan correlation corresponding to a point where a target is detected by a target detecting part 16. Specifically, a level adjustment is performed, centering each point where the target is detected by the target detecting part 16, based on Gaussian function. A strong echo signal is to be detected at a target-detected point thereby the level adjustment (enhancement) of echo signal at such point enables high output level even when echo signal of the target in high-speed movement is weakened by scan correlation. The level adjustment based on Gaussian function can avoid extreme enhancement of echo signal at one point.

摘要： PROBLEM TO BE SOLVED: To provide a target detection system which is capable of fixing an interval in which a plurality of antennas are directed toward a target.SOLUTION: On detection of a reference azimuth θ(S102:Yes), a radar device 11 transmits a first trigger signal S(S103). On reception and detection of a second trigger signal Afrom a radar device 12 (S111:Yes), the radar device 11 stores detection information for a period T/O2 (S112). If the radar device 11 detects the reference azimuth θ(S121:Yes) and keeps the detection information of the second trigger signal Sstored (S122:Yes), the radar device 11 sets an angular velocity ωso as to decrease a rotation velocity of an antenna 101 (S123). If the radar device 11 does not keep the detection information of the second trigger signal Sstored (S122:No), the radar device 11 sets an angular velocity ωso as to increase the rotation velocity of the antenna 101 (S124).

摘要： PROBLEM TO BE SOLVED: To provide an echo image display device that increases the amount of information to be displayed.SOLUTION: A control unit 19 changes resolution of a predetermined area set in a part of a display area of a display unit. The resolution is changed by, for example, changing the number of electromagnetic wave emissions in a predetermined direction in a predetermined area. The control unit 19 issues an instruction to a transmission part 10 to increase the number of outputs of transmission signals per predetermined time in a direction corresponding to a specified magnified area 502. Conventionally, if the resolutions in all the areas on a radar image are increased, data volume is increased. In order to solve the above problem, resolutions are increased only to limited areas in the display area, thereby suppressing data volume and reducing the load on the device.

摘要： PROBLEM TO BE SOLVED: To provide a signal processor of which the countermeasure to a missing is attained by a signal processing method.SOLUTION: A level change (e.g. differential value) between sweeps is detected and verified to a reference pattern to output a level change pattern. The patterns are classified to: a pattern (pattern P) of which the sweep data x(n+1) become larger with respect to sweep data x(n); a pattern (pattern N) of which the sweep data x(n+1) become smaller with respect to the sweep data x(n); and patterns (patterns Z) other than said patterns. A missing discriminating section 153 discriminates an interference on the basis of at least two level change patterns among the level change patterns. For instance, when a change pattern with the sweep data x(n-1) one before the remarkable sweep data x(n) is the pattern N and a change pattern with the sweep data x(n+1) one later is the pattern P, the discrimination is concluded as missing.
