Embodiment Construction

[0064] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0065] see figure 1 , is a schematic structural diagram of a transponder and a radar system according to an embodiment of the present disclosure. Wherein, the transponder 200 is an electronic device that can automatically respond to the signal when it receives a radio inquiry signal. The transponder 200 is erected between the radar 100 and the target 300 . Thus, the transponder 200 can be used to simulate the echo characteristics of the long-distance real target 300 at a short distance, so as to conveniently detect and evaluate the detection performance index of the radar 100 .

[0066] The echo power of the target 300 is not only related to the radar desi...

Abstract

The invention discloses a responder power calibration method and device. The method comprises the steps that multiple echo signals returned by multiple calibration targets which are mutually different in distance to radar in the same scope of the beams of the radar are received; a directional diagram propagation factor calibration value is acquired according to the received multiple echo signals; and the power control factor of a responder of the preset position is acquired according to the directional diagram propagation factor calibration value so as to calibrate the output power of the responder of the preset position. The following beneficial effects can be obtained by applying the scheme: the directional diagram propagation factor calibration value is acquired according to the echo signals of at least two calibration targets so as to acquire the power control factor of the responder to calibrate the output power of the responder. Therefore, the calibrated responder is enabled to accurately simulate the echo characteristics of the target objects so as to perform more accurate detection and assessment on the detection performance index of the radar.

Description

technical field [0001] The present disclosure relates to the technical field of radar testing, and in particular, to a transponder power calibration method and device. Background technique [0002] The transponder can simulate the echo characteristics of long-distance targets at a short distance. Using the transponder can detect and evaluate the detection capability of the radar system, which can greatly save the time and manpower and material costs of the flight test. [0003] In order to accurately detect the detection capability of the radar system, it is necessary to calibrate the output power of the transponder. [0004] In related technologies, when calibrating the output power of the transponder, the following method is generally adopted: first measure the initial output / input ratio coefficient of the transponder, then calculate the ratio of the actual hypothetical distance of the transponder to the simulated distance, and then multiply it by the RCS coefficient, And...
