The ship is able to run a low-grade phase field for extended periods of time, reducing its effective sensor profile by 50%.
In addition, the fleet's detected-at-range is reduced by a multiplier based on the total sensor profile of the 5 highest-profile ships in the fleet, and the total sensor strength of the 5 phase ships with the highest sensor strength values. This effect only applies when the fleet's transponder is turned off.
Fleetwide sensor strength increases - such as from High Resolution Sensors - do not factor into this calculation.
The calculation for determining the final detected-at-range multiplier is S/(S+P), where S is the Sensor profile of your 5 top ships, and P is the sensor strength of your 5 top Phase ships. The multiplier is constrained between 0.25 and 0.95. If you want to reach the maximum multiplier of 0.25, you will need the value from your phase ships to be 3 or more times as much as the value of your sensor profile.
Exactly what the phase field really does, physically speaking, is unknown; its description suggests it may be some kind of phase-based cloaking device, which deflects a portion of the light which hits the ship into p-space, thus reducing its visibility to any kind of sensor or optical instrument.
