Embodiment Construction

[0035] This embodiment is a secondary radar radio frequency transceiver of an aircraft collision avoidance system, which is installed on the top or belly of an aircraft such as figure 1 and figure 2 As shown, both kinds of aircraft can install the TCAS active antenna of this embodiment on the top or belly of the aircraft. Such as image 3 As shown, the aircraft collision avoidance system secondary radar radio frequency transceiver in this embodiment includes a TCAS antenna 10 and a radio frequency active transceiver 30; the TCAS antenna 10 and the radio frequency active transceiver 30 are integrated in an independent module to form a TCAS active antenna 1. Install modem and data processing module 2 in the aircraft. Such as image 3 and Figure 4 As shown; TCAS antenna 10 is a microstrip antenna with at least one radiating element. In this embodiment, four radiating elements are respectively arranged on the disk plane 29 on the microstrip antenna, and are arranged symmetri...

Abstract

The invention provides a secondary radar radio-frequency transceiver of an aircraft anti-collision system. The secondary radar radio-frequency transceiver installed at the top or belly of an aircraftcomprises a TCAS antenna and a radio-frequency active transceiver that are integrated into an independent module to form a TCAS active antenna. The TCAS antenna is a microstrip antenna having at leastone radiating element. The radio-frequency active transceiver includes transceiver assemblies having the number identical with that of the radiating elements; the transceiver assemblies include transmitters for amplifying and sending inquiry signals and receivers for receiving and amplifying response signals; and two active radio-frequency interfaces of the transceiver assemblies are connected with corresponding processing channels in a follow-up modulation-demodulation and data processing module of the corresponding radiating elements respectively. According to the invention, the radio-frequency receivers and the power transmitting circuits are integrated into the four-unit microstrip antenna structure to realize the active TCAS antenna. The secondary radar radio-frequency transceiver has advantages of compact structure, high transceiving efficiency and the like.

Description

technical field [0001] The invention relates to the field of radar, in particular to a secondary radar radio frequency transceiver of an aircraft collision avoidance system (TCAS). Background technique [0002] With the rapid development of the civil aviation industry, the air traffic density is increasing day by day, the route is crowded, and the control of the flight level is stricter. To solve the problem of aircraft flight safety, the aviation industry has developed the S-mode secondary radar and air collision avoidance system ( TCAS) data communication warning system. The TCAS communication system monitors the existence, position and movement of other aircraft in the airspace around the aircraft by inquiring and listening to the transponders of the surrounding aircraft, and sends out Traffic Advisory (TA) or Resolution Advisory (RA) as appropriate, so that pilots can Knowing the traffic situation in the airspace adjacent to your own aircraft, actively take evasive meas...
