Like many stories of this kind, the idea that this person "pioneered the basis" of these technologies seems massively overblown. What she and Antheil patented was a system that used frequency hopping to help guide torpedoes, using a piano roll to switch between the frequencies. They did not "invent" frequency hopping, which had been discussed in the literature for 30 years already.

FWIW, I know some excellent engineers, technologists, professors, etc. who are women, and who also participate in programs to address sexism.
We have a long history of really stupid and unjust sexism, and that's a lot to dig out of. Different people tackle that different ways.
Sometimes I hear of approaches that I don't understand. If I tried to make snap judgments of them, I'd hope I'd usually be right, but I suspect I'd often be wrong.
In general, I think I'm best off focusing on support of things that seem positive.
