Abstract

A system includes units for identifying the location and range of a radar signal source relative to a user'"'"'s vehicle. The system also includes an alarm unit for signalling if the radar source is within a prescribed distance from the vehicle. A readout and display unit displays selected information from the various units of the system.

Claims

1. A system for identifying location and range of a radar unit source comprising:

(A) a radar detector unit;

(B) a remote unit operatively coupled to said radar detector unit to be activated upon said radar detector unit detecting a radar signal from a source;

(C) a control unit connected to said remote unit to be activated by said remote unit;

(D) a distance sensing unit connected to said control unit to detect the distance between said radar detector and the source upon being activated by said control unit;

(E) a location sensing unit connected to said control unit to detect the angular location of the source with respect to said radar detector upon being activated by said control unit;

(F) a readout and display unit connected to said distance sensing unit and to said location sensing unit; and

(G) an alarm unit connected to said distance sensing unit to emit an alarm signal when said distance sensing unit detects a radar signal source located within a prescribed distance from said distance sensing unit.

2. The system defined in claim 1 further including a selector switch on said readout and display unit.

3. The system defined in claim 2, wherein said readout and display unit further includes a multi-colored signal element.
