UWB and ranging - recommended literature

Hello

For a project of mine I need to develop a RTLS and I’ve purchased the MDEK1001 kit. I’ve read through the documentation on the Decawave website and would like to gain a more in-depth knowledge of UWB and location tracking in this context.

Can you recommend textbooks/publications/other literature which a newbie in the field can use for getting sufficient exposure to the subject?

Thanks
