Abstract
A moving target indicator radar system can include a radar transceiver. The system can further include processing circuitry. The processing circuitry can provide a command to move an antenna beam in an azimuth direction. The processing circuitry can further control the radar transceiver to transmit a series of pulses throughout antenna beam motion such that the series of pulses are assembled into Coherent Processing Intervals (CPIs) and such that for a possible target, sequential sets of CPIs are combined covering at least a 3 dB portion an azimuth beam. The processing circuitry can further detect at least one moving target in at least one CPI. Other apparatuses and methods are also described.
Claims20
A moving target indicator radar system comprising:
- a radar transceiver;
- and
- processing circuitry coupled to the radar transceiver, the processing circuitry configured to:
- provide a command to move an antenna beam in an azimuth direction;
- control the radar transceiver to transmit a series of pulses throughout antenna beam motion such that the series of pulses are assembled into Coherent Processing Intervals (CPIs) and such that for a possible target, sequential sets of CPIs are combined covering at least a 3 dB portion an azimuth beam;
- and
- detect at least one moving target in at least one CPI.
A method comprising:
- commanding an antenna beam to move in an azimuth direction;
- controlling a radar transceiver to transmit a series of pulses throughout antenna beam motion such that the series of pulses are assembled into Coherent Processing Intervals (CPIs) and such that for a possible target, sequential sets of CPIs are combined covering at least a 3 dB portion of an azimuth beam;
- and
- detecting at least one moving target in at least one CPI.
A machine-readable medium including instructions that, when executed on a set of processors, cause the set of processors to perform operations including:
- providing a command to move an antenna beam in an azimuth direction;
- and
- controlling a radar transceiver to transmit a series of pulses throughout antenna beam motion such that the series of pulses are assembled into Coherent Processing Intervals (CPIs) and such that for a possible target, sequential sets of CPIs are combined covering at least a 3 dB portion of an azimuth beam;
- and
- detecting at least one moving target in at least one CPI.
