Embodiment 1

[0042] This embodiment provides a method for improving mission reliability based on pan-secondary radar. The method is applied to the electronic system of the interrogation end, and the interrogation machine or auxiliary interrogation resources are started for interrogation according to the target position information and the situation of receiving response information.

[0043] Specific as figure 1 As shown, the inquiry process in this embodiment specifically includes the following steps:

[0044] S101. Extracting inquiry resources that are capable of transmitting and receiving electromagnetic signals, working normally and in an idle state, forming a list of available inquiry resources, and refreshing them at a preset frequency.

[0045] The inquiry resources in this embodiment include inquiry machines and auxiliary inquiry resources, wherein the auxiliary inquiry resources include inquiry resource 1, inquiry resource 2...inquiry resource n, and auxiliary inquiry resources ca...

Embodiment 2

[0055] This embodiment proposes a method for improving mission reliability based on pan-secondary radar. The method is applied to the electronic system of the answering terminal, and the answering machine or matching auxiliary answering resources are used to respond according to the situation of the inquiry signal.

[0056] Specific as image 3 As shown, the method includes the following steps:

[0057] Step 201: extract response resources that can transmit and receive electromagnetic signals, work normally and are in an idle state, form a list of available response resources, refresh according to a preset frequency, and configure working parameters to make the response resources work in the state of receiving inquiry signals.

[0058] The response resources in this embodiment include transponders and auxiliary response resources, wherein the auxiliary response resources include response resource 1, response resource 2 ... response resource m, and the auxiliary response resour...

Embodiment 3

[0069] This embodiment proposes a task reliability improvement method based on pan-secondary radar, which is implemented based on an electronic system, specifically as Figure 5 As shown, the method of the present embodiment includes:

[0070] In step 301, an interrogator or an auxiliary interrogation resource at the inquiring end is enabled to interrogate the target according to the target location information. In this embodiment, the query process in step 301 is specifically as described in Embodiment 1 above, and will not be repeated here.

[0071] Step 302, according to the inquiry signal, enable the corresponding answering machine or auxiliary answering resources of the answering end to receive the inquiry signal and transmit the answer signal. In this embodiment, the response process in step 302 is specifically as described in Embodiment 2 above, and will not be repeated here.

Abstract

The invention discloses a task reliability improvement method based on a generic secondary radar. The method comprises the following steps: starting an interrogator or an auxiliary interrogation resource of an interrogation end to inquire a target according to target position information; according to the inquiry signal, starting a response resource corresponding to a response end to receive the inquiry signal and transmit the response signal; and judging whether the inquiry end receives a response signal, if so, processing the response signal to obtain target related information, and otherwise, failing to establish the information exchange channel. According to the invention, by means of the auxiliary resources, the reliability of the inquiry-response information acquisition mode is improved, and the problem of no response caused by factors such as no responder of a target, no startup of the responder, failure of the responder or shielding of an antenna, occupation of the responder and the like when the secondary radar is used is solved.

Description

technical field [0001] The invention belongs to the technical field of radar communication, and in particular relates to a task reliability improvement method based on pan-quadratic radar. Background technique [0002] The secondary radar is a group of inquiry code signals transmitted by the interrogator through the antenna, the transponder detects the group of inquiry code signals, and judges the content of the code signals, and then the transponder transmits a group of response code signals. The response signal is detected and processed by the interrogator, which measures the distance and azimuth of the target and obtains the content of the response code, etc. Secondary radar has many advantages that primary radar does not have. First of all, since the positioning of the target depends on two active radiations, the transmission power of the same detection distance is much lower than that of the primary radar, and the volume and mass are also reduced accordingly; thirdly, ...
