In modern radars it is no longer usual to measure the transmit to return
time to measure distance. It is very power demanding
in that the transmitted pulse must contain sufficient energy to be
detectable above noise at reception. A lot of power in a short duration
pulse
is expensive and can cause interference with nearby electronic equipment.

I don't think this is so. They still scan.

For satellites it may be a different matter and they may well use
doppler and time of flight. However I do think that the really critical
positioning is done against the fixed stars or other local bodies when
close enough.

Remember that within about the orbit of jupiter, even for the very small
pioneer the force due to solar wind was more than the anomalous
acceleration, and thermal radiation and transmitter power reaction even
greater still. Throw in complex gravitational fields and orientation
rocket bursts (or gyroscope changes) as cameras (for example) point and
acquire the many different objects to be seen and I really doubt there
is much capability to detect the anomalous acceleration or anything like
it.
