1. A method, comprising:
- performing traffic alert and collision avoidance surveillance of a target aircraft using an interrogation over a bottom antenna of own aircraft; and
enhancing determination of a bearing of the surveillance by obtaining a bearing of the target aircraft using an alternative to making a bearing determination based on signal characteristics of a reply to the interrogation.

Abstract
Various avionics systems may be enhanced by methods and systems for bearing reception. For example, a traffic alert and collision avoidance system, or other surveillance system, can be provided with a system or configured for a method of improved bearing reception. For example, a method can include performing traffic alert and collision avoidance surveillance of a target aircraft using an interrogation over a bottom antenna of an own aircraft. The method can also include enhancing determination of a bearing of the surveillance by obtaining a bearing of the target aircraft using an alternative to making a bearing determination based on signal characteristics of a reply to the interrogation.
