Method for reducing angular blur in radar pictures

Method for reducing angular blur in radar pictures achieved in range bin based detection systems, a variable S(x,y) such as amplitude, power or the like being measured as a function of an angle x and a distance y or when x and y only assumes discrete values a variable S(i,j) with i1≦i≦i2 and j1≦i≦j2, the abbreviated way of writing S(x) or S(i) being used when the distance is implicit or irrelevant, characterized in that in each range bin for a plurality of angular values x an expression of the type:

• corrected angular position=angular position+angle correction
• is determined, and in which “angle correction” comprises (partial) derivative(s) of first or higher order S′(x), S″(x), . . . of the measured variable S(x) as a function of the angle x and in which the variable measured at the angular position “angular position” then is moved to the variable in the angular position “corrected angular position”, the moved variable and the variable in “corrected angular position” being processed by adding, maximizing or the like.
