Onboard inquiring and responding integrated equipment for secondary radar

Abstract

The invention relates to the technical field of secondary radar and discloses onboard inquiring and responding integrated equipment for secondary radar. The onboard inquiring and responding integrated equipment specifically comprises an inquiring and responding main engine, an inquiring antenna and a responding antenna, wherein the inquiring antenna is connected with the inquiring and responding main engine; the responding antenna is connected with the inquiring and responding main engine; the inquiring and responding main engine comprises a transmitter module, a receiver module and a time slot controller; the transmitter module and the receiver module are respectively connected with the time slot controller; the time slot switching control is carried out through the time slot controller; the transmitter module and the receiver module work in different work modes at different time points; the working modes comprise an inquiring machine mode and a responding machine mode. Main engines of an inquiring machine and a responding machine are integrated to design the inquiring and responding integrated equipment and can realize all functions of existing onboard inquiring and responding equipment at the same time; compared with equipment with the same kind, for the equipment disclosed by the invention, the weight and the volume are reduced and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of secondary radar, in particular to an airborne secondary radar inquiry and response integration device. Background technique [0002] In the avionics system of modern aircraft, airborne interrogation equipment and airborne response equipment based on secondary radar are commonly used to assist in the realization of ground-air and air-air traffic management. The currently known airborne interrogation and response devices are all independent. When the avionics system needs to realize the two functions of interrogation and response, the interrogator and the transponder are connected by cables to form an interrogation and response system. Among them, the airborne interrogation equipment adopts the mechanical scanning antenna to realize the scanning and tracking of the target. The answering system uses an omnidirectional antenna to receive and transmit signals. [0003] Based on the above-mentioned characteri...
