Description
Technical field
The utility model relates to secondary radar and utilizes field, particularly relates to a kind of distance detection system utilizing secondary radar.
Background technology
Because secondary radar has plurality of advantages, it is made to be widely used in traffic control, enemy and we's identification, information trace etc.The operating distance of secondary radar is determined jointly by the performance of inquisitor and answering machine, and in this operating distance, uplink signal and down link signal can normal transmission and being detected.
The operating distance of secondary radar is generally a few km to hundreds of km, needs to ensure that the space of inquisitor and answering machine must reach this operating distance requirement when carrying out this Indexs measure to it, adds the difficulty that test environment is selected, causes a large amount of manpower and materials consumption.In order to the selection of easy test environment, reduce testing cost, the operating distance that method of equal effects can be adopted to carry out secondary radar detects.Its principle is at responding terminal design fixed attenuator, answering machine can be made to be in receiving sensitivity in closer distance, reach the object of the operating distance detecting secondary radar.This scheme still there is following shortcoming:
Owing to adopting fixed attenuator, during detection between inquisitor and answering machine, corresponding fixed test correlation distance requirement must be met, cause environment for use still limited;
When the frequency of operation of secondary radar higher (as Ka wave band), attenuator attenuates value can produce larger fluctuation with variation of ambient temperature, thus affects the accuracy of testing result.
