Tamar Dane Dor-Ner, a managing partner at Bain, and her husband, Dan Krockmalnic, general counsel for the Boston Globe, talk in a Q&A with HBR editors about how they support each other, how they divide child care and other domestic responsibilities, the benefits each realizes from the other’s job, and what challenges the future might hold.

The local correlation method requires more accurate DOR delay model, and the ambiguity is also more difficult to eliminate. This method has not been applied to Chinese deep space exploration yet. DOR geometric time delay algorithm was studied and validated by two ways. DOR geometric delay and DOR signals were simulated, and the local correlation method was used to get DOR delay measurement, which was different from the simulated true DOR delay in 0.2 ps. CE-2 orbit data were also used to calculate VI.BI geometric delay an DOR geometric delay. Transformation between the above two delays was demonstrated. The difference between VLBI delay transferred from DOR delay and the direct calculated VLB delay was under dozens of picosecond. The research results validate the exactitude of DOR geometric time delay algorithm and can be used in the Chinese Lunar, Mars and Venus deep-space exploration projects in the future.

Aiming at the demand of more accurate interferometry in the following deep space exploration, a novel interferometry scheme based on signal combination is proposed and analyzed. By studying the mainstream signal combination algorithms, an improved Sumple algorithm based on phase comprehension is put forward. This algorithm is more efficient than the original Sumple algorithm, and moreover its combined signal has the same phase performance as that of the reference signal, which is the premise of antenna array technique used for interferometry. Finally, tests are conducted by using phased array data and simulated DOR signal data. The processing results show that the signal combination improves the delay estimation accuracy of interferometry, and is of special meaning in deep space exploration. [ABSTRACT FROM AUTHOR]
