Abstract
A radar apparatus provided with a transmitter for periodic transmission of mutually disjunct groups of N radar transmitter pulses and provided with a receiver for the receipt of echo signals of the groups of radar transmitter pulses. The radar apparatus includes a video processor for processing echoes in a listening time observed between two of the mutually disjunct groups of radar transmitter pulses. By choosing a suitable staggering of the pulses in a group, the target range and velocity may be unambiguously determined.
Claims15
A radar apparatus comprising:
- a transmitter configured to periodically transmit mutually disjunct groups of N radar transmitter pulses, with N=4, 5, 6, . . . ;
- a receiver configured to receive echo signals of the radar transmitter pulses;
- and
- a video processor configured to detect possible objects based on the received echoes and to estimate parameters of the possible objects,
- wherein the video processor is configured to simultaneously process echoes from an entire group of said mutually disjunct groups in a listening time observed between two of the mutually disjunct groups of radar transmitter pulses.

A method for operating a radar apparatus comprising:
- transmitting periodically mutually disjunct groups of N radar transmitter pulses, with N=4, 5 ,6, . . . ;
- and
- applying simultaneously received radar echo signals from an entire group of said mutually disjunct groups to a video processor to estimate parameters of a possible detected target during a listening time between two of the mutually disjunct groups of radar transmitter pulses.
