摘要： PROBLEM TO BE SOLVED: To control radiation of unnecessary spectrum while stably generating sampling pulses with a high amplitude and a narrow pulse width, to avoid the increase of the cost required for reducing the unnecessary spectrum, and to facilitate the time scanning of sampling timing.SOLUTION: A sampling pulse generator generates impulse-like short pulses required for the transmission or impulse-like short pulses required for sampling of the received wave without using a high-speed switching element, by an equivalent signal processing to orthogonal frequency division multiplexing modulation in a transmission pulse generating section 10 and a sampling pulse generating section 20. Hence, the radiation of unnecessary spectrum is controlled while stably generating sampling pulses with a high amplitude and a narrow pulse width, the increase of the cost required for reducing the unnecessary spectrum is avoided, and the time scanning of sampling timing is facilitated.

摘要： PROBLEM TO BE SOLVED: To provide an interference eliminator capable of performing sampling in the same phase within the range of an engineering allowable error even though an observation point or a signal source is different. SOLUTION: This interference wave elimination circuit comprises: an A/D converter 402-0 provided in any of a plurality of signal lines to perform sampling processing of an input signal corresponding to its own self at a sampling time designated by a reference sampling signal to be temporal reference of sampling; A/D converters 402-1 to 402-n provided in the other connection lines to perform sampling processing of the input signal corresponding to their own selves at a sampling time designated by a shift modulation sampling signal obtained by performing shift modulation of the reference sampling signal; and a sampling adjustment circuit 420 for separately generating a shift modulation sampling signal by shifting change timing of the reference sampling signal on the basis of an offset value separately set in each A/D converter 402-1 to n.

摘要： PROBLEM TO BE SOLVED: To achieve a radar having high near distance resolution in a narrow band. SOLUTION: The pulse radar based on a principle calculating a distance from a time difference until a pulse signal is received by being reflected from a target has: an adaptation filter for removing a transmission waveform interfering with a feedback line from a transmission circuit from a receiving waveform; and a phase change detection filter for taking out the change of a phase change generated by the arrival and end of a response wave from the target. Since the pulse radar has no need of completing the transmission pulse before the response wave arrives, the pulse radar has no need of shortening pulse width in order to improve the near distance resolution.

摘要： PROBLEM TO BE SOLVED: To improve detection performance of a target by corresponding a response wave period from a target to a Fourier transform period. SOLUTION: Transmission time of transmission pulse from a pulse generation circuit 5c is obtained by a pulse window synchronous circuit 7b of a synchronous circuit part 7 formed between a transmission circuit part 5 and a receiving circuit part 6. Sampling data begins to be supplied from a serial-parallel conversion circuit 6c to an FFT circuit 6d at the timing where the transmission pulse is generated. Finish time of a window of FFT is regarded as time elapsed by a period of the transmission pulse from start time of a window. Within the time of the window, sample data for FFT is obtained, and a receiving waveform is converted into data of an frequency axis from data of a time axis. Thereby, the response wave period from the target corresponds to the FFT period, raw data can be converted into frequency domain without producing wave-shaped distortion, and radar performance, such as recognition performance and distance resolution performance, can be improved.
