摘要： A detection apparatus and a detecting method may be provided, which are capable of specifying with a smaller data amount an area where a transmission signal is blocked when performing a detection using transmission and reception signals. In a two-dimensional data structure stored in a memory 9 of a weather radar apparatus 1, a height of an obstacle 11 may be specified by a single parameter ϕ when the obstacle 11 blocking a transmission signal B1 is located in an observation area AR. A signal processor 8 may process a reception signal based on blocking area specifying information.

摘要： The purpose is to reduce interference of a radio wave transmitted from an antenna with other radio waves. An antenna device 8a is provided, which may include a rotatable antenna 10, a time information acquirer 24, an antenna rotation start reference time setter 32, a periodic signal acquirer 22, and a rotation control processor 33a. The time information acquirer 24 may acquire time information. The antenna rotation start reference time setter 32 may set an antenna rotation start reference time based on the time information. The periodic signal acquirer 22 may acquire a periodic signal repeated at a constant cycle larger than a time error of the time information. The rotation control processor 33a may determine a rotation start timing at which the antenna starts rotating, based on the antenna rotation start reference time and the periodic signal.

摘要： A pulse compression radar for performing pre-distortion is provided, which has a configuration simplified in circuit structure. A radar apparatus (pulse compression radar) 1 includes an antenna 10 configured to externally transmit a transmission signal transmitted by a power amplifier 16 and receive a reflection signal caused thereby as a reception signal. The radar apparatus 1 includes a reception circuit 41 configured to propagate this reception signal to a radar image creating module 26. The radar apparatus 1 corrects beforehand, by utilizing the transmission signal (feedback signal) transmitted from the power amplifier 16, a transmission signal to be inputted into the power amplifier 16 so as to cancel distortion of the transmission signal caused by amplification effect of the power amplifier 16. Further, a circuit where the reception signal passes and a circuit where the feedback signal passes share a part of each other.
