Data Farming Around the World Overview - Cornwallis Group

280 THE CORNWALLIS GROUP XIV: ANALYSIS FOR SOCIETAL CONFLICT AND COUNTER-INSURGENCYIn several data farming experiments the different sensors' validity was checked. To easethings, the scenario described above was further simplified (see Figure 8).In our scenario, the team examined the sensor's performance for different approachcorridors for the hostile micro-light plane. By doing so, the team could analyse the effect ofdifferent terrain features.Figure 8: Simplified base case scenario.Data Farming ExperimentsAfter some preliminary experiments and looking at single simulation runs to get familiar withthe model and its user interfaces, three different data farming experiments were performed.In the first experiment we distinguished between day and night, thus varying theparameters for the luminance and the temperatures of the target object and the background.In the second experiment the team had a look at different levels of attenuation. Thusrepresenting the whole bandwidth from excellent to very bad weather conditions, that is fromclear sky to dense fog.Finally, the team was convinced themselves that the detailed physical ABSEM sensordelivers more realistic perception probabilities than a simple, purely probability based sensor.In a third experiment the team decided to equip the observer either with a detailed opticalsensor or with a very simple and abstract sensor (comparable to the one implemented inMANA).
