Description of the invention (Technical field The present invention relates to a tracking system and a radio rangefinder in particular to measure the distance between a remote transponder and a reference position. BACKGROUND OF THE INVENTION The system is used for self-contained reference Position recognition and positioning mobile transponders are known techniques and have been used in many environments including aviation. For example, RF transmitters located at a reference location are used to send signals to identify data codes received by the mobile transponders to be tracked. After receiving the encoded signals Shihe determines the code # number to the address of the mobile transponder. The mobile transponder sends back a signal at a frequency different from the original transmitted signal received by the receiver at the reference position. Information on the auxiliary and conditional functions of the mobile transponder can be added to Above the retransmitted signal. When the receiver receives the retransmitted signal, the identification and location of the addressed mobile repeater can be determined. However, although the location of the mobile repeater is known, its distance from the reference position cannot be easily Therefore, the purpose of the present invention is to provide a new radio rangefinder and radio ranging system to measure the remote The distance between the transmitter and the reference position.

Description of the invention (2) Provided according to one aspect of the invention The radio ranging system includes: a transmitter to transmit a signal received by a remote transponder; at least one remote transponder to receive the transmitted signal and repeat the gyro signal in response to the transmitted signal; a receiver to receive the gyro signal; and processing The device is used to make the transmitted and slewing signal have a relationship and generate an output signal to the remote transponder to the interface The distance between the devices is proportional to 0. In a preferred embodiment, the processing device includes a device that determines the delay between the transmitted and gyro signals and a device that generates an output signal in response to the decision device. It is also preferred that the radio ranging system further includes addressing The device is connected to the transmitter to address the transmitted signal to identify the particular remote transponder. In this case, the 'mother to) remote transponder includes an address detection device to detect the address and current location of the acoustic radiation. The received signal of the normal address enables the remote device to forward a gyro signal when it is received. The present invention provides an advantage in the design of the radio rangefinder which is simple yet allows accurate distance measurement between the reference position and the remote repeater It can be done in a schematic diagram. The implementation of the present invention will be described in detail with reference to the accompanying diagram ^ _ \: FIG. 1 is a block diagram showing the overall combination of all the line-electric distance measuring systems according to the present invention; The block diagram of the radio measurement system of the system part; Figure 3 is the block diagram of the chip code generator forming the part of the circuit of Figure 2; and _ -5- This paper standard is applicable to the Chinese National Standard (CNS ) A4 specification (completion of 210X297) (please read the precautions on the back before filling in this page), ΤΓ '-v, * -rw ^ the special one of the mobile transponder-address modulation II 丨 modulated signal At this time, the modulation signal is represented by each line ^, the description of the invention (Figure 4 is a graphical representation of the original transmitted signal, the gyro signal received from the transponder, and the time delay between the two signals). The best sentiment is now referred to Figure i, which shows the radio ranging system, and is generally referenced by the reference wire 1 〇 Table 7 ^. The system 10 includes a radio rangefinder 1 2 and many remote actions ^ 1 4, shown in only one. The radio range finder 12 sends _S to each mobile transponder H to receive the late modulation signal Ms mobile transponder receives β, and the sensor 14 checks to determine whether the transponder is sufficient. The received modulation number is not a fixed transfer of two P to α. The mobile transponder i 4 receives the normally addressed hammer change signal and responds by forwarding back to No. 5 R s. When the radio rangefinder # i 2 receives the J rotation number R s, the rotation signal and the transmitted modulation signal M s are related. In this case, an output signal is generated to represent the radio range finder 2 and the addressed mobile repeater. 1 The distance between 4. Turning now to Figure 2, the radio rangefinder 丨 2 has a better display. As can be seen, the radio rangefinder includes the transmitter 12 accepting input from the code generator 22. The code generator 22 receives the input from the microcontroller 24 and the clock 26 and also supplies the input to the balance modulator 28. The balance modulator 28 also receives the input from the clock 26 and supplies the output to the mixer 30. The mixer also accepts the input from the receiver 32 and supplies the output to the passband filter 丨 4. The output of the frequency band pass wave 3 4 is supplied to the external demodulator 3 6.

Description of the invention (4) / ': Ί ratio. Because the radio rangefinder 12 has a connection 32 and a transmitter 20, the signal can be transmitted and received simultaneously making it a full-duplex system. Γ £ · B5 ^ / Figure 3 preferably shows the code generator 22 and: ^ spelling; ‘see, it is made up of a series of receiving delay elements 40, 42 and 44 respectively. The delay element is combined with the feedback path 46. In particular, the output from the last delay element 44 and the intermediate delay element 42 are combined in the modulo-2 adder 48 and fed back to the input of the first delay element 40. The content of the code generator 22 is initiated by the microcontroller 24. The operation of the radio ranging system 10 will be described. When it is desired to determine the distance between the mobile transponder 14 and the radio rangefinder 2, the microcontroller 24 provides input to the code generator 2 2 to activate it, so that the code generator 2 2 generates an output representing the action switch The distance of the device 14 from the radio rangefinder 12 is determined. The address code output AC (see FIG. 3) is supplied from the code generator 22 to the transmitter 20. The transmitter then generates and transmits a quasi-spread spectrum carrier signal with frequency £ 1 modulated by the address code. The address code A c is also supplied to the balanced modulator 28 at an internal carrier signal that is the same as the signal transmitted by the transmitter. When the modulated signal M s is transmitted, all mobile transponders 14 receive the transmitted modulated signal. Each mobile transponder 14 includes an address detection circuit designed to detect a modulation signal whose address code modulation corresponds to the address assigned to the mobile transponder. If the transmitted modulation signal received by the mobile transponder does not match the address code assigned to the live transponder, the mobile transponder ignores the received modulation signal. However, if the modulation signal received by the mobile transponder is modulated by an address code equivalent to the address assigned to the mobile transponder, the mobile transponder works and forwards the slewing signal R s with a carrier frequency gate ° ^ ι · ^^ 1 ^^ 1 — ^ 1 ^^ 1 — ^ 1 ^ II—-—I — ^ 1 II — V—► J -β (Please read the precautions on the back before filling this page)

Description of invention (5 When the rotation signal Rs is received by the receiver 32, it is added to the mixer 30. The mixer is also received from the balance The modulated internal carrier signal of the modulator 28. Because the modulated internal carrier signal is the same as the originally transmitted modulated signal M s, the mixer 30 has the original transmitted and gyro signal. Figure 4 shows the internal modulated signal Both the signal and the slewing signal Rs are modulated by the address code ac. The delay π between the carrier and the slewing signal and the duration T c of the address code are shown. The output of the mixer 30 is determined by the passband 3 4 Filter and pass through the external demodulator 3 6 to make the rotation and the internal carrier signal have a relationship to generate a delay between the original transmitted modulation signal Ms and the rotation signal Rs ^ · directly proportional to the analog voltage output. Delay 〇 · can be expressed by the following formula: therapy = d / c; where: d is equal to the distance between the radio range finder 2 and the remote mobile transponder 14; and c is equal to the propagation speed of the radio signal passing through the environmental medium. Because both the speed of light and the delay are known, the external demodulator 36 The specific voltage output is proportional to the distance between the classic line electrical ranging bar 12 and the designated address mobile repeater 14. The analog voltage output can be corrected and converted to digital form to produce a digital value representing the distance d. Digital signal The representative distance d can be used to push the display to provide a visual indication of the distance. The maximum distance d can be measured by the system. The measurement is determined by the equation: d = cxTc; where: (1) C is the propagation speed of the radio signal passing through the environmental medium it travels; And T c is the duration of the address code generated by the code generator 22.

However, it should be understood that in this case, the signal cannot be transmitted and received at the same time. Also, the analog output voltage can be corrected and used to produce an analog display that provides a visual indication of the distance d And do not need to be converted to digital form.
