Sounding signal for object detection in a radar system

A method for a sounding signal, comprising:

• configuring an antenna to transmit a sounding signal into an environment;
• controlling beam forming and beam steering of the antenna for a determined direction;
• transmitting the sounding signal in the determined direction;
• detecting a first reflection of the sounding signal from a first reflection point in the environment;
• determining a location of the first reflection point from the reflection of the sounding signal at a first time;
• determining the first reflection point is within a direct line of sight from the antenna;
• detecting a second reflection of the sounding signal from a second reflection point at a second time after the first time;
• determining the second reflection point is not within the direct line of sight from the antenna;
• storing the first and second reflections as a reflection set associated with the sounding signal transmitted at a first transmission time;
• and
• determining a location of at least one object as a function of comparing multiple reflection sets, wherein the first reflection point deflects the sounding signal to the second reflection point.

A processing system, comprising:

• a memory storage unit;
• and
• at least one processing unit configured to:
• control beam forming and beam steering of the antenna for a determined direction;
• initiate transmission of the sounding signal in the determined direction;
• detect a first reflection of the sounding signal from a first reflection point in the environment;
• determine a location of the first reflection point from the reflection of the sounding signal at a first time;
• determine the first reflection point is within a direct line of sight from the antenna;
• detect a second reflection of the sounding signal from a second reflection point at a second time after the first time;
• determine the second reflection point is not within the direct line of sight from the antenna;
• store the first and second reflections as a reflection set associated with the sounding signal transmitted at a first transmission time;
• and
• determine a location of at least one object as a function of comparing multiple reflection sets wherein the first reflection point deflects the sounding signal to the second reflection point.
