Aircraft radar arrangement
First Claim
1. In an on-board radar arrangement for an aircraft including a search radar having a sharply focused transmit/receive antenna oriented generally in the direction of travel of said aircraft for providing a first reception signal, and an antenna direction control for providing an antenna orientation signal and further including a radar warning system for detection and analysis of remote radar having an omnidirectional receiving antenna for providing a second reception signal, the improvement comprising;
- a first circuit for providing said first reception signal to the radar warning system,a second circuit for providing said orientation signal to said radar warning system, andmeans associated with said radar warning system including means for utilizing said first and second reception signals to enhance the reception resolution in the direction of flight of said aircraft in order to achieve increased sensitivity of remote radar detection in said direction of flight of said aircraft, and means for utilizing said orientation signal and said first and second reception signals to distinguish between the detection of radar located in said direction of flight and the detection of radar not located in said direction.

Abstract
In an aircraft on-board radar arrangement including a search radar and a radar warning receiving system, an additional receiving branch is provided to which are fed foreign radar signals received by the sharply focused transmit/receive antenna of the search radar, with the output of the additional receiving branch being connected to the radar warning receiver. This results in a greater angular resolution and a considerable increase in range, which again leads to a more detailed and early detected of threatening situations. By using already available components and because of the simple configuration of the additional receiving branch, additional costs remain low.
