Abstract

Embodiments are directed to representing radio frequency (RF) signals in a visualization using particle bursts. In one scenario, a computer system instantiates RF signal sources in a virtualization, where each RF signal source is configured to emit RF signals. The computer system then generates a stream of particle bursts to represent at least one of the emitted RF signals, and provides a visualization that shows the instantiated RF signal sources along with the generated particle bursts representing the emitted RF signals. In some cases, the visualization may be used to illustrate an anti-access, aerial denial (A2AD) environment. In other cases, the visualization may be used to illustrate network communications using particles, where each particle represents network data packets.

Claims

1. A method, implemented at a computer system that includes at least one processor, for representing radio frequency (RF) signals in a visualization using particle bursts, the method comprising:

instantiating one or more simulated RF signal sources in a visualization, each RF signal source being configured to emit RF signals;

generating a stream of particle bursts to represent at least one of the emitted RF signals; and

providing a visualization that shows the one or more instantiated simulated RF signal sources along with the generated particle bursts representing the emitted RF signals.

2. The method of claim 1, wherein the visualization includes a plurality of simulated RF signal sources, each simulated RF signal source emitting RF signals at different rates.

3. The method of claim 1, wherein generating a stream of particle bursts comprises aggregating the emitted RF signals into groups of particle bursts.

4. The method of claim 3, wherein the particle burst groups include a specified amount of RF signal photons.

5. The method of claim 1, wherein the visualization illustrates one or more jamming devices configured to emit a specific type of RF signals.

6. The method of claim 1, wherein the visualization illustrates one or more RF signal detection devices configured to detect RF signals and RF signal reflections.

7. The method of claim 1, wherein providing a visualization further comprises displaying the particle bursts on a spectrum plot which is synchronized with the stream particle bursts from the emitter.

8. A computer program product comprising at least one computer-readable storage device having stored thereon computer-executable instructions that, when executed by one or more processors of the computing system, cause the computing system to instantiate a user interface comprising the following:

a communication network comprising a plurality of network nodes and communication signals, wherein the communication signals travel between origin and destination endpoints, the communication signals comprising data packets; and

a plurality of inter-node communication pathways configured to carry the communication signals from the respective origins to the respective endpoints through the plurality of network nodes, wherein the data packets are represented as particles in the user interface, such that the particles are visualized as traveling from origin to destination endpoints through the network nodes.

9. The computer program product of claim 8, wherein different properties of the particles are represented as different attributes of the data packets.

10. The computer program product of claim 9, wherein data packets of a first type are illustrated as having a first color, and data packets of a second, different type are illustrated as having a second, different color.

11. The computer program product of claim 10, wherein the assigned colors change dynamically based on the speed of the data packet, thereby indicating which network nodes are faster or slower.

12. The computer program product of claim 10, wherein particles at inefficient nodes are illustrated as backing up, thereby allowing data traffic jams to be visualized.

13. The computer program product of claim 9, wherein dropped data packets are illustrated as falling from the communication network.

14. The computer program product of claim 9, wherein the user interface illustrated allows network nodes to be moved to avoid or reduce interference.

15. A computer system comprising the following:

one or more processors;

an instantiation module configured to instantiate one or more RF signal sources in a virtualized anti-access/area denial (A2AD) environment, each RF signal source being configured to emit RF signals;

a particle burst generator configured to generate a stream of particle bursts to represent at least one of the emitted RF signals in the virtual A2AD environment; and

a visualization generator configured to provide a visualization that shows the one or more instantiated RF signal sources along with the generated particle bursts representing the emitted RF signals in the virtual A2AD environment.

16. The computer system of claim 15, wherein the visualization generator is further configured to provide additional functionality in the particle visualization including battlefield management elements, planning elements, flight test observation, playback and simulation in the virtual A2AD environment.

17. The computer system of claim 15, wherein the visualization generator is further configured to generate a virtual network operations center (NOC) representing network operations and network devices on a battlefield.

18. The computer system of claim 17, wherein the visualization generator illustrates one or more animations in the NOC to show network communications using particles, each particle representing one or more data packets.

19. The computer system of claim 15, wherein the visualization generator instantiates one or more signal jammers within the virtual A2AD environment, and further presents a mapped out flight course through the virtual A2AD environment that avoids the signal jammers.

20. The computer system of claim 19, wherein the visualization generator determines how many particles are emitted by each signal jammer, and which flight course results in a minimal amount of particles coming into contact with an aircraft.
