Abstract :
In this paper performance of Walsh-Hadamard sequences (WHS) for binary encoding of radar signals is described. It is shown that between WHS with length 8, 16 and 32 it is possible to find a set of orthogonal sequences with good properties. Probability of correct range detection of selected WHS in presence of active noise jamming is described and it is compared with cases when Barker code is used for binary encoding of radar signals and when widely used linear frequency modulation inside pulse duration is used to spread spectrum of radar signals.
