A bone-chilling cold snap below minus 43 degrees Celsius kept Aaranya away from her field site near the Quiet Lake batholith. Canada switched from the Imperial to the Metric system only a few months ago on April 01, 1975. So, Aaranya is keeping track of both the systems during her January 1976 field trip. She is still studying the Yukon-Tanana terrane for clues about the deathly hallows.

Prof. Scamander is back at the Frazden school in Lapland, so Aaranya has no valid reason to ignore the textbook she is commissioned to write.

It is time to start thinking about the first SARtastic beast and the first paper that Aaranya had read when she started her research on radar imaging. This beast is from the MeriKotka house, so the episode starts with a brief mention of DJ Bohm (its founder).

Aaranya reads some content from a 1999 paper on a near-field 3-D synthetic aperture radar (SAR) imaging algorithm. As she is thinking aloud and this is a crude draft, you will hear her talk about how this paper led her down a certain path and led her to other research papers from 2001, 2015, 2021, and 2022.

As this beast is from the MeriKotka house, you will hear how the founder of the house inspired Aaranya over the years and how a dialogue between DJ Bohm and a biologist helped Aaranya finally understand what the 1975 song (Kuinka Voit by Hector) from scene 3 was telling her about the formative field.

Aaranya is referring to the following papers:

• Historical roots of gauge invariance (2001)


• 3-D radar imaging using range migration techniques (1999)


• Deep learning and quantum annealing methods in synthetic aperture radar (2021)


• A Review of Synthetic-Aperture Radar Image Formation Algorithms and Implementations: A Computational Perspective (2022)


• Overcoming polar-format issues in synthetic aperture radar multichannel autofocus (2015-2016)

Note: As this podcast is a work of fiction, everything herein is imaginary with some random facts. You will hear a few seconds of the MeriKotka house song (Kaikista maailman maista by Petri Laaksonen) because our first SARtastic beast belongs to MeriKotka. Aaranya will croak again.
