... vibrations of the satellite also imply a degradation of the signal. We then associate to these vibrations a jitter (resp., pointing) PSF. The detector also adds additional blurring due to the ... Finally, the detected signal is further degraded by the electronics PSF. Computation of (21) is computationally intensive. One alternative is to compute the FT of the PSFs. T...

... that m k n < | a n | . 3. Proof of the theorem Proof of Theorem 1.1.Letm =min |z|=k |p(z)|. If p( z)hasazeroon|z|=k,thenm = 0 and the result follows from Lemma 2.8. Henceforth, we suppose that all the zeros of p(z) ... this result contradicts the fact that |a 1 |>k. Hence, the polynomial D α 1 p(z) must be of degree (n - 1). On the other hand, since all the zeros...
