Abstract
The utility model discloses a nonlinear structured detecting radar which arranges an antenna together with a receiving and transmitting front terminal. The utility model comprising a detecting antenna and a detecting radar host computer, is characterized in that the front terminal of the detecting radar host computer is provided with a metallic shield box, and further provided with a metallic antenna socket, a wave absorbing material and a connecting conductor. Wherein, the wave absorbing material is arranged at the front terminal of the metallic shielding box. The metallic antenna socket is arranged at the front terminal of the wave absorbing material. The detecting antenna is arranged at the metallic antenna socket. One end of the connecting conductor is connected with the detecting antenna, while the other end of the connecting conductor crosses through the metallic antenna socket and the wave material as well as the metallic shielding box. The other end of the connecting conductor also is connected with the front terminal of the detecting radar host computer arranged inside the metallic shielding box. Compared with the traditional nonlinear structured detecting radar, the system signal of the utility model does not pass through the attenuation on cable, the transmitting power of the system is reduced while the receiving sensibility is improved; furthermore, the situation that the whole radar can not normally work due to frequent pull and damage of the cable contacting terminal; the operating flexibility of the whole radar is improved, too. Therefore, the utility model has excellent practicability and economical efficiency.
Description
Technical field
The utility model relates to detection radar, specifically is exactly the non-linear knot detection radar of ultrahigh frequency that a kind of exploring antenna and detection main frame receiving and transmitting front end are integrated in one.
Background technology
PN junction in the electronic devices and components can give off higher hamonic wave again under the irradiation of ultrahigh frequency electromagnetic signal, and the object in the nature does not have similar physical characteristics.Non-linear knot detection radar is exactly to utilize this class feature of electronic devices and components to search the electronic target of being hidden, and this type of target comprises wiretap, sending box etc., so non-linear knot detection radar is important safe and secret checkout facility.
Because conventional exploring antenna such as microstrip antenna, thereafter bigger to radiation signal, if detection radar main frame receiving and transmitting front end is excessively near the exploring antenna back side, then this signal electronic devices and components that will shine in the main frame receiving and transmitting front end make it to give off the higher hamonic wave signal again, thereby the jamming target signal causes the system can't operate as normal.In view of above reason, present non-linear knot detection radar often is designed to detection radar main frame and two independent sectors of exploring antenna, and with 1~2 meter long high frequency cable connection, as SFT-50-2, every meter loss is about 1dB between the two.Because there is loss in high frequency cable to high-frequency signal, adopt this scheme to sacrifice performances such as the emissive power of non-linear knot detection radar and receiving sensitivity; And because the effect that involves of cable, the operation of detection radar is dumb, and rupture easily in cable plug place.
Summary of the invention
The utility model is for example overcomes the above-mentioned shortcoming that existing non-linear detection radar exists, and a kind of exploring antenna that connects without cable that provides and survey the non-linear knot detection radar of ultrahigh frequency that the main frame receiving and transmitting front end is integrated in one.
