Conformal active reflect array for co-site and multi-path interference reduction

摘要

A system and methods for co-site and multi-path interference mitigation are presented. A reflection signal is received from at least one aircraft surface at a sensor near a receiver antenna, and a conformal reflective phased array antenna coupled to at least one aircraft surface is configured to steer the reflection signal. The reflection signal is steered using the conformal reflective phased array antenna to reduce an amplitude of the reflection signal at the receiver antenna based on the reflection signal received at the sensor.

1. A method for co-site and multi-path interference mitigation, the method comprising:
receiving a reflection signal from at least one aircraft surface at a sensor near a receiver antenna; sending signal characteristics of the reflection signal from the sensor to an antenna controller; configuring by control of the antenna controller a conformal reflective phased array antenna coupled to the at least one aircraft surface to steer the reflection signal; steering the reflection signal using the conformal reflective phased array antenna to reduce an amplitude of the reflection signal at the receiver antenna based on the reflection signal received at the sensor; and phase shifting the reflection signal based on a measured angle of arrival of the reflection signal at the sensor.
