Abstract:
A method for beam forming in direction finding systems with two identical groups (W.sub.L, W.sub.R) of transducers, each group comprising at least one transducer, where in an electronic signal processing devicea) a complex differential signal ,=- is derived from the complex output signals - of the two groups of transducers;b) a magnitude summation signal R.sub.BSum is formed from the absolute values of said transducer group output signals according to equation (7)R.sub.BSum =a.multidot..vertline..vertline.+b.multidot..vertline..vertline., with a+b=2;andc) for generating a resulting output signal (R.sub.HYP), said magnitude summation signal R.sub.BSum) is divided by the magnitude (.vertline..vertline.) of said complex differential signal ().
