Technique for changing a range gate and radar coverage

A radar system to detect an object and to determine if the object is moving relative to the radar system, comprising:

• a radar transmitter to transmit radar energy;
• a radar receiver to receive radar energy associated with the transmitted radar energy in a plurality of receive radar beams;
• and
• a radar processor to process the received radar energy and to generate a detection table having a plurality of indicators, each one of the indicators indicative of a detection of the object, the plurality of indicators comprising a first plurality of indicators associated with the plurality of receive radar beams in a first time period and a second plurality of indicators associated with the plurality of receive radar beams in a second time period and to combine at least two indicators from among the first and second plurality of indicators.

A method of detecting an object with a radar system and determining if the object is moving relative to radar system, comprising:

• transmitting radar energy;
• receiving radar energy associated with the transmitted radar energy in a plurality of receive radar beams;
• and
• associating the received radar energy in selected ones of the plurality of receive radar beams with received radar energy in other selected ones of the plurality of receive radar beams.
