Abstract
In one embodiment a communication system comprises a radiofrequency (RF) transmitter, an antenna communicatively coupled to the RF transmitter to direct an RF signal in a first direction, a laser ranger mounted to the antenna to direct a pulsed laser signal in the first direction and receive reflected laser signals from a rotorblade, and logic to determine a measure of interference resulting from a rotorblade, provide the measure of interference to a radiofrequency (RF) transmitter, and shutter an RF transmission signal from the RF transmitter in response to the measure of interference. Other embodiments may be described.

A method, comprising:
- determining at an apparatus, a measure of interference indicating a degree to which a rotorblade interferes with an RF transmission signal being transmitted by an RF transmitter, the measure of interference based on reflected laser signals, wherein the reflected laser signals are generated from a pulsed laser signal reflected by the rotorblade;
- providing the measure of interference to a radiofrequency (RF) modulator;
- and shuttering the RF transmission signal for the RF transmitter based on the measure of interference.
A system, comprising:
- a radiofrequency (RF) transmitter;
- an antenna communicatively coupled to the RF transmitter to direct an RF signal in a first direction;
- a laser ranger mounted to the antenna, the laser ranger configured to:
- direct a pulsed laser signal in the first direction;
- and
- receive reflected laser signals from a rotorblade;
- logic to determine, based on the reflected laser signals, a measure of interference indicating a degree to which the rotorblade interferes with an RF transmission signal;
- logic to provide the measure of interference to the RF transmitter;
- and
- logic to shutter the RF transmission signal for the RF transmitter based on the measure of interference.
An aircraft comprising:
- a system, comprising:
- a radiofrequency (RF) transmitter;
- an antenna communicatively coupled to the RF transmitter to direct an RF signal in a first direction;
- a laser ranger mounted to the antenna, the laser ranger to:
- direct a pulsed laser signal in the first direction;
- and
- receive reflected laser signals from a rotorblade;
- logic to determine, based on the reflected laser signals, a measure of interference indicating a degree to which the rotorblade interferes with an RF transmission signal;
- logic to provide the measure of interference to the RF transmitter;
- and
- logic to shutter the RF transmission signal for the RF transmitter based on the measure of interference.
