Abstract: An autonomous radar transmitting system transmits radar signals which simulate the presence of a police- manned radar station. A system controller runs pseudo- randomizing programs to select signal parameters such as the pulse width and pulse separation as well as the signal power of generated radar signals. The radar output of the system is therefore sufficiently random to prevent a detecting circuit from identifying it in the time it takes for a motorist with a radar detector to reach the radar source. This system is battery powered and a photovoltaic panel is provided to recharge the battery, thus giving the system a long lifespan. The controller detects the battery power level and modifies the parameters of the generated signals in response to low battery levels. A radiation detector is also provided through which radiation signals may be input from a remote control. The input radiation signals may be used to suspend system operation or modify the signal parameters.

Abstract: An autonomous radar transmitting system transmits radar signals which simulate the presence of a police-manned radar station. A controller runs pseudo-randomizing programs to select the width of a radar pulse transmitted as well as the time lapse between subsequent pulses. The radar output of the system is therefore sufficiently random to prevent a detecting circuit from identifying it in the time it takes for a motorist with a radar detector to reach the radar source. This system is battery powered and a photovoltaic panel is provided to recharge the battery, thus giving the system a long lifespan. Also provided is an infrared detector through which infrared signals may be input to the controller. Thus, external control is provided without making the system susceptible to tampering or vandelism. Most of the electrical components are enclosed in a weatherproof casing capable of being mounted in a number of discrete, convenient locations.
