摘要： A transmitting unit emits a short pulse wave which satisfies a predetermined spectrum mask from an antenna into space. A receiving unit receives a reflected wave produced by an object existing in space of the short pulse wave emitted by the transmitting unit. A signal processing unit analyzes the object based on an output signal from the receiving unit. The transmitting unit has a pulse generator which outputs pulse signals each having a predetermined width at a predetermined frequency, and a burst oscillator which receives the pulse signal output from the pulse generator and performs an oscillation operation for time corresponding to the width of the pulse signal to output the short pulse signal. A width and a cycle of the pulse signal and an oscillation frequency of the burst oscillator are set such that almost an entire main lobe of a spectrum of the short pulse wave falls within a range of 24.0 to 29.0 GHz in the predetermined spectrum mask, and that a radiation power density to an RR radiowave emission prohibited band held by the predetermined spectrum mask is lower than a peak radiation power density of the main lobe by not less than 20 dB.

摘要： Provided is a technique capable of accurately calculating the radiation power of an object to be measured using a spheroidal coupler even when there is a non-negligible loss in a measurement system.A phase rotating unit including a variable phase shifter, a two-branch circuit, and a reflective element that is connected to one of the branched outputs of the two-branch circuit is inserted between a receiving antenna and a power measuring device. The maximum value and the minimum value of power measured by a power measuring device when the variable phase shifter changes a phase are calculated. An output reflection coefficient of a coupler is calculated from the ratio of the maximum value to the minimum value, and an input reflection coefficient of an object to be measured which is approximate to the output reflection coefficient is estimated. In addition, an input reflection coefficient of a reference antenna which is used instead of the object to be measured is estimated in the same way. The total radiated power of the object to be measured is calculated on the basis of the estimated input reflection coefficients and the reception power when the power measuring device directly measures the output of the receiving antenna.

摘要： A transmitting unit of a short-range radar includes a first pulse generating unit, a second pulse generating unit, an oscillator and a switch, and while complying with the spectrum mask specified for a UWB short-range radar, emits a predetermined short pulse wave not interfering with the RR prohibited band or the SRD band into the space. The first pulse generating unit outputs a first pulse having the width larger than the width of the short pulse wave in a predetermined period. The second pulse generating unit outputs a second pulse having the width corresponding to the width of the short pulse wave during the period when the first pulse generating unit outputs the first pulse. The oscillator oscillates only during the period when the first pulse generating unit outputs the first pulse, and the switch is turned on and passes the output signal from the oscillator only during the period when the second pulse generating unit outputs the second pulse, thereby to emit the output signal from the switch into the space as the predetermined short pulse wave.

A device under test is placed in a position of one of the two focal points such that a center of radiation of a radio wave substantially coincides with the focal point, and a receiving antenna is placed in an position of an other one of the two focal points. The device under test is caused to radiate a radio wave and the radiated radio wave is reflected at the wall surface to allow the receiving antenna to receive the radio wave.
