Save the Date: I will be on Coast to Coast next Wednesday night for two hours with an introduction to my GenSix, Ancient Cataclysms and Coming Catastrophes presentation
While they are saying, "Peace and safety!" then destruction will come upon them suddenly like labor pains upon a woman with child, and they will not escape. 1 Thessalonians 5:3
Where there is no vision, the people perish, Proverbs 29:18
The military is starting off the new year with a bit of introspection... Is it possible that forces are getting a little too comfortable and complacent with what they think, know, and understand? Are they falling victim to their own confirmation biases, risking total surprise by something lurking just over the horizon, beyond their line of sight? To mitigate this, they resolved to broaden their Aperture (an all-seeing eye) on the Operating Environment. They want to preclude being sucker-punched. We can glean insights critical to our situational awareness from their posturing. You might want to do the same, and so we shall.
Synthetic Aperture Radar (SAR)
While researching the newly deployed advanced technologies rushed to combat the bush fires in Australia, I ran across the word aperture. This caught my attention as I also ran into the word several times in military news at the end of 2019. In optics, an aperture is a hole or an opening through which light travels. I am beginning to see the manifestation of the cultic All-Seeing Eye with is supposed limitless and omnipresent vision in the news from astronomy to the military.
An optical system has many openings or structures that limit the ray bundles also known as pencils of light. These structures may be the edge of a lens or mirror. In general, the aperture determines the light and brightness of images.
"It is quite reasonable to conclude that some form of photomap will become the standard general map of the future. [Evidence shows that it has been deployed]. Photomapping appears to take reasonable advantage of future data sources like high altitude aircraft and satellite imagery, says Sandia National Laboratory."
What is Synthetic Aperture Radar (SAR)?
Sandia National Laboratories is deploying environmental monitoring, earth-resource mapping, and military systems for broad-area imaging at high resolutions. This imagery must be acquired at night or during inclement weather. Could these be the swarms of drones that people are beginning to see? Synthetic Aperture Radar (SAR) provides such a capability. Synthetic Aperture Radar (SAR) systems take advantage of the long-range propagation characteristics of radar signals and the complex information processing capability of modern digital electronics to provide high-resolution imagery. Synthetic Aperture Radar (SAR) complements photographic and other optical imaging capabilities because it is not limited by the time of day or atmospheric conditions and because of the unique responses of terrain and cultural targets to radar frequencies. In essence, this system is mapping terrain and assets that will eventually make war against God and His assets, which includes you and me.
How Does Synthetic Aperture Radar (SAR) Work?
A detailed description of the theory of operation of Synthetic Aperture Radar (SAR) is complex.
Consider an airborne Synthetic Aperture Radar (SAR) imaging perpendicular to the aircraft velocity as shown in the figure below. Typically, Synthetic Aperture Radar (SAR) produces a two-dimensional (2-D) image. One dimension in the image is called range (or cross-track) and is a measure of the "line-of-sight" distance from the radar to the target. Range measurement and resolution are achieved in Synthetic Aperture Radar (SAR) in the same manner as most other radars: range is determined by measuring the time from transmission of a pulse to receiving the echo from a target and, in the simplest Synthetic Aperture Radar (SAR), range resolution is determined by the transmitted pulse width, i.e. narrow pulses yield fine range resolution.
I am inserting this technical piece from Sandia, not to bore you to tears, but so that when you see these aircraft or drones, you will know what they are doing and their mechanism of operation (what they are doing). The other dimension is called azimuth (or along-track) and is perpendicular to the range. Synthetic Aperture Radarís (SAR) ability to produce relatively fine azimuth resolution differentiates it from other radars. To obtain fine azimuth resolution, a physically large antenna is needed to focus the transmitted and received energy into a sharp beam. The sharpness of the beam defines the azimuth resolution. Similarly, optical systems, such as telescopes, require large apertures (mirrors or lenses which are analogous to the radar antenna) to obtain fine imaging resolution. Synthetic Aperture Radar (SAR) is much lower in frequency than optical systems. These require long antennas however now airborne radar can collect data while flying and then process the data as if it came from a physically long antenna. The distance the aircraft flies in synthesizing the antenna is known as the synthetic aperture. Narrow synthetic beam-width results from the relatively long synthetic aperture yielding finer resolution images.
