EM Detection Sensors
EM Detection Sensors
EM Detection Sensors passively detect shields and active search sensors of other ships, as well as electronic emissions from inhabited planets.
EM Sensor Sensitivity
EM Sensor Sensitivity is a technology found under Sensors and Fire Control. Each level of the technology increases the range at which the sensor can detect a target. More sensitive sensors are more expensive and require more raw materials.

Total Sensor Size
Total Sensor Size is not based on any technology; all options are available from the beginning. Available sizes run from 0.1 HS to 50 HS. Increments of 0.1 HS are available for sensors from 0.1 to 1 HS; sizes from 1 HS to 50 HS are available in 1 HS increments. The following attributes are affected by sensor size:
EM Sensor Sensitivity is multiplied by Total Sensor Size to determine the overall sensitivity of the sensor. The overall sensitivity is the range, in millions of kilometers, at which the sensor can detect a target of signal strength 1000. For example, a sensor with EM Sensor Sensitivity 8 that takes up 3 HS can detect a strength 1000 target at 24,000,000 km (8 * 3 = 24).
HTK is 0 for sensors smaller than 1 HS, and 1 for sensors 1 HS or larger.
Base crew size is 5. This is multiplied by sensor size, and fractions are truncated (so 0.1 HS sensors require no crew).
Cost from the EM Sensor Sensitivity chart is multiplied by Total Sensor Size, and fractions are rounded to the nearest whole number. Half is rounded to the nearest even whole number; for example, both 3.5 and 4.5 are rounded to 4.
Materials required from the EM Sensor Sensitivity chart are multiplied by Total Sensor Size, and fractions are rounded to the nearest 0.25. Half is rounded to the nearest even 0.25, so 1.125 (9/8) and 0.875 (7/8) are both rounded to 1 (8/8).
Hardening is based on Electronic Hardening technology, found under Sensors and Fire Control. Each level of the technology reduces the chance that a microwave weapon will destroy the sensor if it is hit. Greater levels of hardening cost more and require more raw materials, but they do not effect sensor size, crew required, or sensitivity.
