Multistatic radar system for airport monitoring
First Claim
1. A method for monitoring targets on a runway by means of emitting modules and receiving module, wherein said emitting modules and said receiving modules are alternately distributed along each one of longitudinal sides of said runway and in that it includes emitting orthogonal signals by said emitting modules at a rate of at least two orthogonal signals per emitting module, receiving signals in said receiving modules coherently with emitting orthogonal signals by said emitting modules, and detecting an object on said runway based on a distribution of said modules into meshes each including three neighbor bistatic pairs of emitting module and receiving module and on a radio location of said object through triangulation and interferometry in at least one mesh.

Abstract
The present disclosure relates to a method for monitoring targets on a runway, wherein emitting modules and receiving modules are alternately distributed along each one of longitudinal sides of the runway. Orthogonal signals are emitted in a narrowband by the emitting modules and coherently received in a coherent manner by the receiving modules. An object is detected on the runway on the basis of a distribution of the modules into meshes each including three pairs of neighbouring emitting modules and receiving modules and on the basis of a radio location of the object through triangulation and interferometry in at least one mesh. The modules are also used for analyzing a target moving on the runway, and for monitoring the trajectographies of an air target in the surroundings of the runway.
