Synthetic aperture simulator. I could never get finding to build so decided to do it myself.

I built a synthetic aperture sonar / radar simulation engine so I could generate endless amounts of procedural generated scenes to train a world model. Data for sonar is especially hard to come by.

Why aren't they using Claude code 20x for 200/month?

I think ppl only care about how Claude or codex does.

I am writing synthetic aperture sonar/radar simulator and image formation code from scratch.

Too many codes or old or gate kept behind proprietary walls. Many are old and don't use the newest acceleration techniquea to make the simulation fast. Additionally, none of them scale using aws. I want SAS/SAR image to be easy to generate for anyone.

I have a similar finding for a website I made that collates college town bar specials and live music. Using agents with vision models works but it's not as straightforward as one would initially think. U can check out the results here. https://www.nittanynights.com

What is S? Also, NVIDIA RTX 4500 Ada is missing.

> but there's a massive financial reality here.

Not a chance. The DoD has massive pockers which and INCREDIBLY SPREAD OUT. You can't underestimate how spread this money is. The DoD has maybe a 64 GPU cluster and ALMOST NO ONE USES IT FOR DEEP MODEL TRAINING. Even contractors end up working with DGX boxes to do all their training.

As of 2023, I was doing the largest Deep learning training runs out of anyone I have known in the industry and I've been in the industry for 20 yeras. The second best groups behind mine were using 4 GPU locally machines that they had to purchase on contract.

There's no way the DoD can train these models themselves, not even close. They are COMPLETELY DEPENDENT ON INDUSTRY. I was the PM for a DARPA program in 2023 and SAME PROBLEM. They had no compute or would rely on university compute if a program had a university partner. YOU HAVE NO IDEA HOW FAR BEHIND THE DOD IS IN THIS SPACE.

I would think claude code would help make a quick dent in boosting reactos capabilities. Curious what others think.

Ask people to do things for you. Then you will learn how to work with something/someone who has faults but can overall be useful if you know how to view the interaction.

I wonder if any of these findings help us better understand me/cfs.

A phased array is made up of lots of channels.

In sar, the speed of the medium doesn't change, in ultrasound it changes every few mm.

I can assure you it's not sonar for people. The signal processing is way more complicated than traditional sonar. Sonar also has number roughly 10 channels. Ultrasound transducers have 10x more. The array is generally 2d and not planar either where sonar is generally a 1d planar array.

I do synthetic aperture radar signal processing for a living. I make the SAR pictures you see (or use for your research). I think a big part of the cost is the signal processing. You need fast A/D converters too. The software though to make a steerable ultrasound beam is not trivial by any means. Also, you have multiple sound speeds to account for in layered media where you dont know the layers occur or what their sound speed is. Another really hard problem.
