Embodiment 1

[0071] In order to solve the technical problem of low efficiency of the flight test method for secondary radar performance assessment in the prior art, the embodiment of this application provides an efficient secondary radar performance assessment method. First, the assessment system using this assessment method is introduced. .

[0072]There are three aircraft in the assessment system, namely: the aircraft to be assessed equipped with the secondary radar to be assessed, the first target aircraft equipped with the first transponder, and the second target aircraft configured with the second transponder. The aircraft may specifically be an airplane, or other flight equipment, such as an airship, which is not limited herein. In the following description, the method in the embodiment of the present application will be described in detail by taking the aircraft as an example.

[0073] In this embodiment of the application, the aircraft to be assessed is called A, the first target ...

Embodiment 2

[0114] Based on the same inventive concept as the first embodiment of the present application, the second embodiment of the present application provides a secondary radar performance assessment system, including:

[0115] An aircraft to be assessed equipped with a secondary radar to be assessed;

[0116] a first target aircraft equipped with a first transponder;

[0117] a second target aircraft equipped with a second transponder;

[0118] Wherein, at the first moment, the aircraft to be tested carries out a first flight process from a preset position along a first direction at a first speed, and flies toward the first target aircraft and the first target aircraft during the first flight process. Two target aircrafts send a first inquiry signal; wherein, the first target aircraft and the second target aircraft fly along the first direction at a second speed at a second moment before the first moment, and the the first speed is greater than the second speed;

[0119] When th...

Abstract

The invention discloses a secondary radar performance examination method and examination system. The examination system comprises a to-be-examined air vehicle with a to-be-examined secondary radar, a first target air vehicle with first answering equipment, and a second target air vehicle with second answering equipment. In addition, the method includes: the to-be-examined air vehicle carries out a first flight process from a preset position along a first direction at a first speed at a first time and sends a first inquiry signal to the first target air vehicle and the second target air vehicle during the first flight process; and when receiving a first response signal fed back by the first target air vehicle or the second target air vehicle during the first flight process, the to-be-examined air vehicle performs performance testing of orientation coverage, orientation resolution, and pitching coverage of the to-be-examined secondary radar based on the first response signal and a first relative position.

Description

technical field [0001] This application relates to the technical field of secondary radar, in particular to a secondary radar performance assessment method and assessment system. Background technique [0002] Secondary radar uses a closed-loop method of inquiry and response to complete the detection of cooperative targets, and has been widely used in the fields of civil aviation and military aviation. Among them, azimuth coverage, azimuth resolution, and elevation coverage are important performance indicators of secondary radar, which must be assessed through platform test flights. [0003] For the above-mentioned key indicators, the traditional assessment method has formulated corresponding flight test subjects, and independently completed the performance assessment of azimuth coverage, azimuth resolution, and pitch coverage through typical flight test routes. For example, the traditional flight test route for azimuth coverage is a double-aircraft circling "8" or "S" fligh...
