a. The radiation metric used in the radiation design margin for sensor background calculations shall be agreed with the customer.
b. The radiation metric used in the achieved RDM shall be chosen as representative of the sensor bandwidth critical to the mission objectives.
NOTE 1 It is highly dependent upon the sensor design and application. It can be provided by the customer in the equipment requirements.
NOTE 2 As with single event effects, the MRDM required can be dependent upon the phase of the mission, and local environment.
c. Where the background has been simulated, a comparison between simulations and irradiation results for the sensor (or a representation of the sensor) shall be performed in order to gauge the level of error in the modelling process.
NOTE The uncertainties associated with the calculation of the background are very much dependent upon the sensor or instrument design and method for calculating detector background, including, where appropriate, the use of experimental data.
