The loss of signal detectability in band-pass limiters

Capture and Spurious Target Generation Due to Hard Limiting in Large Time-Bandwidth Product Radars

“…This may be mathematically accompished by a simple omission of the factors A 0 and R in Eq. (2). The limiter output hence is given by…”

“…If the expanded signals overlap less than completely, there will be a proportionate reduction of the false target magnitudes (4). Let one input signal be given by A 0 exp j(2nfot + bt 2 ) and the other by a scaled, time-and phase-shifted version of the first signal:…”

Detection Performance of Soft-Limited Phase-Coded Signals

“…The details of pulse compression and matched-filter techniques are described elsewhere [1][2][3][4][5][6]. The effect of limiting on the limiter output SNR has been described for single and multiple sine waves in Gaussian noise [7][8][9][10][11][12][13]. The detection performance of hard-limited phase-coded signals, with compression ratio up to 63:1, has been studied by Klein and Fujita [14].…”
