摘要： The invention provides a pulse radar apparatus, and a control method thereof, that permits to readily downsize and to lower its cost and allows information on an object to be detected in high precision by removing an influence of noise when a gain of a variable gain amplifier is discontinuously changed corresponding to detected distance, with a simple configuration. A variable gain amplifier 135 configured to adjust a gain corresponding to a distance gate is used to be able to detect weak reflected wave from a distant object and to amplify a reflected wave from a short distance with a low gain. An offset noise from the variable gain amplifier 135 is prepared together with interference noise and self-mixing noise in advance as a replica signal of unwanted wave and the replica signal is removed from a baseband signal in detecting the object T.

摘要： Provided is a pulse receiver capable of receiving a burst signal and decoding the burst signal with a bit error rate reduced to a target value or less by controlling a determination threshold such that decoding success rate is equal to or less than a predetermined value. A decode unit 140 decodes a pulse train 20 to information 30, counts the number of decoding successes for a predetermined time period and outputs the counted number (decoding success rate DR) to a control unit 150. The control unit 150 uses as a basis the decoding success rate DR communicated from the decode unit 140 to control the set value of reference voltage Vth used in the comparator 130.

摘要： A delay control device that controls a relative delay time between two signals and is easy to be miniaturized is provided. Signal routes 111 to 114 and signal routes 121 to 124 in a first signal route part 110 and a second signal route part 120 have different delay times. By selecting any one of the four signal routes 111 to 114 in the first signal route part 110 and any one of the four signal routes 121 to 124 in the second signal route part 120, it is possible to finely change a relative delay time between two input pulse signals.
