The invention relates to a method for monitoring the functioning of an NOx sensor, which is arranged in an exhaust gas channel of an internal combustion engine and is located downstream from an NOx storage catalytic converter. The aim of the invention is to detect the faulty functioning of the NOx sensor in a simple manner in order to be able to take appropriate measures if necessary. To this end, the mass of NOx absorbed by the NOx storage catalytic converter is determined within a diagnostic period using a measurement signal of the NOx sensor. At the same time, an absorbed NOx target mass is calculated using a model for the NOx storage catalytic converter. A ratio of the NOx mass to the NOx target mass is then compared to predetermined limit values to determine the functioning of the NOx sensor. The aim of the invention is alternatively accomplished by measuring a duration time for a complete NOx regeneration of the NOx storage catalytic converter. A specified duration time is also calculated for the NOx regeneration using a model for the NOx storage catalytic converter and using a measured or calculated NOx load state. A ratio of the measured duration time to the specified duration time is then compared to predetermined limit values to determine the functioning of the NOx sensor.

The invention discloses a detection method of a small target of a feature space, realizing small target detection of the feature space through steps of star position location, reference star selection, star and potential target division, track association cancelling noise, and the like. Because a detection algorithm of small moving target with a moving night sky background of a feature space based on distance is adopted, two stars are selected to be used as reference stars, different motion characteristics among the stars, and the target and a noise point are fully utilized to directly divide the stars, the potential target and the noise in a two-dimension feature space domain. Compared with three reference stars selected by the background technology on calculation of a similarity measuring function, an error square sum and a curve inflection point in a three-dimension space, the invention reduces the calculation amount because one star is decreased. Because the track continuity of the target is directly utilized to detect a track, a process that a potential target point set is mapped from the three-dimension space to the two-dimension space to be detected is avoided, and the detection is simpler and more practical.
