Abstract: It is critically important for modern radars to make fast and unambiguous measurements of a target's range and Doppler frequency shift. One of the promising ways is to use quasicontinuous signals in radars with special transmission and reception mode. Quasicontinuous signals have a thumbtack shape of an ambiguity function and can be used in radars with common aerial. This study presents the quasicontinuous transmission and reception mode of a pseudorandom amplitude and phase-shift keying signals in radars with common aerial. The Time-Frequency Cross-Correlation (TFCC) function of such signals is used for describing their coherent processing result. The TFCC function approximation is given taking into account the receiver path blanking during the probing signal transmission. An example of signal clutter immunity estimation is given based on TFCC function approximation and determined statistical averaging of distribution density of the total clutter power along delay and the Doppler frequency shift.
