Abstract
In a sonar system using a large array multielement sonar detector to detect reflected signals sent out by a sonar ping generator, the sent out sonar ping generator sends out varying frequency sonar signals during each ping, where the frequency is neither monotonically increasing or monotonically decreasing.
Claims12
A method, comprising:
- a) insonifying a volume of fluid with one or a series of sonar pings, wherein the volume of fluid contains zero or more objects, wherein at least one of the one or a series of sonar pings has a frequency which changes significantly during the sonar ping, and wherein the frequency change is neither monotonically increasing nor monotonically decreasing.
A method, comprising:
- a) insonifying a volume of fluid with at least one or a series of sonar pings, wherein the volume of fluid contains zero or more objects, wherein at least one of the one or a series of sonar pings has a pseudo random frequency pattern, wherein the pseudo random frequency pattern is not a uniform frequency nor a monotonically increasing frequency nor a monotonically decreasing frequency.
A method, comprising:
- a) insonifying a volume of fluid with at least one or a series of sonar pings, wherein the volume of fluid contains zero or more objects, wherein at least one of the one or a series of sonar pings has a pseudo random frequency pattern.
