In this paper, a new direct data domain least squares (D3LS) approach is developed for multiple target detection in space-time adaptive processing (STAP). The advantage of the D3LS technique is that it does not rely on any statistical information of the interference as opposed to conventional STAP algorithms. The modified version of D3LS when more than one target is in a radar scenario will be discussed. This is equivalent to forming multiple beams simultaneously while suppressing all other interference at the radar receiver. Numerical simulations show that multiple beams are directed towards target directions correctly and maintain their gain constraints along those directions such that the target signal intensities or complex amplitudes can be estimated.
