Definitions
- the invention relates to a method for determining a position of an object, which comprises at least one nonlinear component, in particular a semiconductor component. Furthermore, the invention relates to a device for determining a position of an object, which comprises at least one nonlinear component, in particular a semiconductor component.
- the invention further relates to a system, in particular a vehicle, a trailer or a container, which comprises such a device and / or carries out such a method.
- NLJ detector non-linear junction detector
- the primary high-frequency radiation induces a voltage at the pn junctions of the corresponding semiconductor component, which acts like a current-carrying conductor and thus induces its own electromagnetic field
- the second and / or third harmonics in turn can be received and evaluated by a receiving and evaluation unit via a receiving antenna.
- DE 10 2013 011 220 A1 discloses a method for determining the distance of an object, which comprises at least one non-linear component, the disclosure of which is incorporated in its entirety by reference in this application. This is a method for determining the distance of an object which contains at least one non-linear component which, when irradiated with a high-frequency pulse-shaped or periodically frequency-modulated transmission signal, generates an object signal with twice and / or triple the frequency of the transmission signal and emits it again.
- the object of the invention is to create a method, a device and / or a system of the type mentioned at the outset that allows a position of an object that has at least one nonlinear component to be determined.
- a method for determining a position of an object which comprises at least one non-linear component, in particular a semiconductor component, which is set up to irradiate with high-frequency transmission signals from at least two different positions, object signals with twice and / or three times the frequency of the respective transmission signal generated and emitted again.
- the device according to the invention for determining a position of an object which comprises at least one nonlinear component, in particular a semiconductor component, which, when irradiated with high-frequency transmission signals from at least two positions, receives object signals with double and / or triple frequency (2nd harmonic, 3rd harmonic) to generate the respective transmission signal and emit it again.
- the invention provides a system, in particular a vehicle, trailer or container, which comprises such a device or a device developed as described below.
- a system in particular a vehicle, trailer or container, which comprises such a device or a device developed as described below.
- This ensures that the object position of an object can be determined with at least one non-linear component.
- high-frequency transmission signals are emitted from at least two different positions.
- Each transmission signal that strikes the object, more precisely the non-linear component generates an object signal with twice / or three times the frequency of the respective transmission signal.
- the generated object signals are emitted again and the position of the object can be determined on the basis of the emitted object signals. It has been found that this method is less susceptible to malfunction and the achievable accuracy is higher. Furthermore, this method only determines the position and not only the distance to an object.
- the device according to the invention and its further developments are designed accordingly in order to carry out the method according to the invention and the further development of the method in a suitable manner. These further developments of the device have the same advantages which have been described with regard to the method.
- the method can include the following features: determining the angle of incidence with a maximum backscattering power of each transmission signal, and determining a position of the object by triangulation based on the angle of incidence with the maximum backscattering power of each transmission signal and on the basis of the positions from which the transmission signals are made were broadcast.
- the position of the object is determined by triangulation on the basis of the irradiation angle thus determined with maximum backscattering power of each transmission signal and on the basis of the positions from which the transmission signals were emitted. This specifies a simple but robust method that allows the position of the object to be determined in a simple and robust manner.
- the method can comprise the following steps: irradiating the object with at least two transmission signals emitted from different positions by at least one transmission device; Receiving the object signals emitted by the nonlinear components at twice and / or three times the frequency of the transmitted signals by at least one receiving device; Determining a backscattering power of the object signals taking into account an angle of incidence of the send signals. These steps are preferably carried out before the angle of incidence is determined with a maximum backscattering power of each transmission signal. This provides a way of determining how the backscattering power is to be determined. First, the object is irradiated from two different positions by at least one transmission device.
- the object signals emitted by the nonlinear components of the object are then received by at least one receiving device and the backscattering power is determined taking into account the angle of incidence of the transmission signals.
- the backscattering power is determined taking into account the angle of incidence of the transmission signals.
- the method steps are preferably carried out in the aforementioned order, furthermore preferably in immediate sequence.
- the backscattering power of the object signals for determining the angle of incidence is integrated with the maximum backscattering power in an angle-resolved manner over the entire frequency range of the object signals.
- the integral of the backscattering power of the object signals is drawn for each angle of incidence over the entire frequency range, and the maximum backscattering powers are determined in an angle-resolved manner.
- the method can provide that a position of maximum distance and a position of minimum distance is determined on the basis of the shape of the antenna lobes, in particular an opening angle of the main lobes, of the transmitting and / or receiving devices and on the basis of the angles of incidence with the maximum backscattering power.
- a certain measurement tolerance which is defined by the shape of the antenna lobes, in particular the opening angle of the main lobes. This measurement tolerance is taken into account accordingly in this embodiment of the method.
- an angle range can be assigned to each angle of incidence with the maximum backscattering power.
- these are the opening angles of the main lobes. These angular areas of each angle of incidence with the maximum backscattering power intersect and there are intersections which define the area in which the object is located. These intersections define a position of maximum distance and a position of minimum distance.
- the position of the object is determined from the position of maximum distance and the position of minimum distance.
- the position of the object is then determined from the initially determined position of maximum distance and the position of minimum distance, for example by determining an average value, so that the position of the object is determined as being midway between the position of maximum distance and the position of minimum distance.
- mathematical methods other than the determination of an average value are also conceivable, such as, for example, the determination of a center of gravity, a surface spanned by the intersection points of the angular regions.
- the method can provide that the angle of incidence of each transmission signal is set by mechanically and / or electronically pivoting the antenna lobes of the transmission devices.
- Mechanical pivoting is realized by pivoting the entire device or the transmitting device.
- Electronic swiveling can be implemented, for example, in that only certain parts of an array of a transmitter emit transmission signals of a certain angle, and then other parts of the array emit transmission signals with a different angle of incidence. It is hereby achieved that the transmission signals are transmitted with a time delay only in a certain angular range and thus a scanning of an entire swiveling range of the transmission device is realized.
- the method can provide that each transmission signal is emitted from a single transmission device and is received by a single reception device, the transmission device emitting transmission signals in a first position and the reception device receiving object signals and then, preferably by movement under its own power or by transport , in further positions again emits transmission signals and receives object signals. It is provided for this embodiment of the method that only one transmitting device and one receiving device are required. This is preferably attached to a system, such as, for example, a vehicle, a trailer or a container, in order to be transported to various positions from which transmission signals are emitted and object signals are received. This also specifies a method which makes it possible to determine the position of the object using a simply designed device which has only one transmitting device and one receiving device.
- the method created thereby provides for a more time-consuming change in the position of the device for carrying out the method, but makes it possible to implement a method according to the method with a comparatively simple device.
- the method can provide that each transmission signal is emitted from a different transmission device, which are each arranged in different positions, and the respective object signal is received by a respective reception device assigned to the respective transmission device.
- transmission signals are emitted from different transmission devices, which are each arranged in different positions.
- the device thus comprises a plurality of transmitting devices which allow transmitting signals from different positions to be transmitted in a short time or simultaneously and to receive the object signals generated by the transmitting signals with the receiving devices assigned to the respective transmitting devices. In this way, a method is specified which makes it possible to implement an implementation in accordance with the method without a relatively time-consuming change in the position of the device for carrying out the method.
- the device preferably provides a circuit device which is set up to determine the angle of incidence with the maximum backscattering power of each transmission signal and to determine the position of the object by triangulation based on the angle of incidence with the maximum backscattering power of each transmission signal and on the basis of the positions .

- the position of the object can be reliably determined by a device with a simple configuration.
- the device can provide that the device comprises at least two transmission devices for emitting transmission signals, each in different positions.

- an array can be formed for this purpose, which has a plurality of subarrays or antennas spaced apart from one another as transmitting devices. Individual, differently positioned antennas can also be provided as transmitting devices. A combination of arrays, subarrays and / or antennas is also possible.
- the distances between the transmitting units and the receiving units can be of different sizes or equidistant.
- An equidistant arrangement has the advantage that a high signal-to-noise ratio can be achieved. Different distances have the advantage that the number of ambiguities can be reduced.
