Abstract :
We investigate the separation of a linear mixture of secondary surveillance radar (SSR) replies impinging on an M-element antenna array. At base-band, a received SSR signal consists of a binary sequence with alphabet {0, 1}, modulated by a complex exponential due to the residual carrier frequency. We present two algebraic algorithms to compute the separating beamformers by taking into account the particular modulation format of the received signal.
