I thought the thinned array curse was specifically referring to transmitting coherent arrays?
In terms of synthetic aperture receiving arrays, I'm not sure the absolute timestamping accuracy you can extract from say, the on-off encoded minute marker on the 60kHz reference signal will be good for much of any synthetic array used at HF or above. I'm guessing their transmit antenna has a Q of 100 or so, meaning that the on-off encoding will have a rise or fall time in the millisecond ballpark. Wikpedia tells me NPL used to have a "fast code" 100 bit per second signal which would imply that their antenna Q is not more than 1000.
