| 69 | Passive ranging of an airborne emitter by a single non-maneuvering or stationary sensor | US569462 | 1984-01-09 | US4613867A | 1986-09-23 | Martin Golinsky |
| A method for passively determining the range of a target vehicle relative to a non-cooperating moving test platform is disclosed. The method includes the steps of moving the test platform along a single linear path at a constant speed, while simultaneously performing a succession of bearing and frequency measurements on a radiant signal emitted by the moving target vehicle. Similarly, the test platform may remain stationary so that its velocity is zero. The measured parameters, along with knowledge of the test platform's own position and velocity, permit the range to the emitter, its velocity and its transmitted frequency to be determined. | ||||||

| PROBLEM TO BE SOLVED: To efficiently perform measurement of a light axis and a distance image to be performed to guarantee the quality of an on-vehicle camera, in cooperation with an image recognizing device by utilizing an on-vehicle navigation device. SOLUTION: This method for inspecting on-vehicle camera is used in a vehicle monitoring system, where an image of a scene in front of a vehicle is picked up by a camera 2a (2b) mounted on a vehicle body and the running state of the vehicle is recognized by an image recognizing device 20, the light axis and the distance image are measured to decide whether they are proper, so as to guarantee the quality of the camera by the image recognizing device 20, the judged result is displayed via a display monitor 52 connected with the on-vehicle navigation system 5, for the promotion of adjustment. In addition, when the light axis is decided as being abnormal in normal/abnormal decision of the measurement of the light axis, replacement of mounting members is promoted by selectively instructing a mounting member with the shape in which a range to deviate from a proper range of a reference pattern becomes the smallest from among plural prepared mounting members. | ||||||

| PURPOSE:To continuously and accurately detect a running state, by simultaneously transmitting an ultrasonic wave and an electromagnetic wave during the running of a moving vehicle, and arranging a detector in a running path side to receive said ultrasonic wave and electromagnetic wave while operating and detecting the running state of the moving vehicle. CONSTITUTION:Light or an electromagnetic wave such as a radio wave is transmitted from a synchronous signal transmitter 17 in synchronous relation to the burst wave transmitted from a burst wave transmitter 19. Ultrasonic sensors 21a, 21b receive the ultrasonic wave intermittingly transmitted from an ultrasonic sensor 15. The ultrasonic waves received by the sensors 21a, 21b are inputted to frequency measuring circuits 29a, 29b to measure the altitude of frequency. This measured value is inputted to an operating and judging circuit 31 to operate the speed of a moving vehicle and judgement such that the moving vehicle approaches or goes away. An initial condition is inputted to this judgement and the speed and advance direction of the moving vehicle are displayed by a display circuit 35 and the running state of the moving vehicle can be continuously and accurately detected. | ||||||

| PURPOSE:To realize the highly-exact measurement of a distance based on a reference signal which is correct constantly even when the relative distance between transmission and reception sides is changed, by providing high-stability signal sources on the transmission and reception sides respectively, and further providing a reference signal source on the third side. CONSTITUTION:The carrier wave of a VLF signal received by an antenna 31 and a signal obtained by converting the output signal of a rubidium oscillator 33 with a frequency control terminal by a frequency synthesizer 36 are supplied to a phase comparator 34. The comparator 34 discriminates whether the output signal of the synthesizer 36 lags or leads in relation to the VLF signal, and delivers a signal proportional to the amount of the phase shift. This signal is integrated by an integrator 35 having a long time constant so as to obtain a control output proportional to a value obtained by integrating a phase difference for a long time. This control output is made to be a control signal of the oscillator 33 and thereby the phase difference is compensated. Accordingly, the output of the oscillator 33 is made synchronous in phase with the VLF signal with high exactitude, and the frequencies of rubidium oscillators 12 and 21 on the transmission and reception sides which are synchronized in phase with each other by the VLF signal are in accord with high exactitude. | ||||||

| PURPOSE:To measure a line of sight speed irrespective of the speed of an acceleration applied to a flying object, by a method wherein a plurality of oscillators, which produce a frequency deviation in proportion to the speed of acceleration and have frequency deviation rates being different from each other, are placed on the flying object.

Two waves are received by an antenna 5 at an observing point 4, they are detected and amplified by a receiver 6, are sent to frequency measuring device 7, and a line of sight speed to the observing point 4 of the artificial satellite 1 is determined irrespective of the speed of acceleration utilizing a relation between the received frequency and frequency deviation charateristics of a wave thereof to a known acceleration of a frequency oscillator and between the received frequency and a Doppler effect. | ||||||
