Abstract

A radar detector includes a graphical display for displaying a spectral representation of detected signals.

Claims

1. A radar detector, comprising:

a display screen including means for defining a plurality of character positions geometrically across the display screen including at least a first row having a first plurality of character positions arranged in a linear manner,

means for scaling the first row to correspond to at least one predefined microwave frequency band, wherein each of the first plurality of character positions is scaled to correspond to a contiguous segment of the predefined microwave frequency band,

means for detecting a microwave signal within the at least one predefined microwave frequency band,

means for identifying the contiguous segment of the predefined microwave frequency band in which the microwave signal is detected,

means for storing at least a first predefined character, and

means for driving the display screen to display the first predefined character in the character position in the first row which corresponds to the identified segment.

2. The radar detector of claim 1, wherein the detecting means comprises means for detecting a microwave signal within any one of a plurality of predefined microwave frequency bands, and wherein the scaling means comprises means for selectively scaling the first row to correspond to the predefined microwave frequency band in which the microwave signal is detected.

3. The radar detector of claim 2, wherein the plurality of predefined microwave frequency bands include the Ka band, the K band and the X band, and wherein the detecting means scans each of the predefined microwave frequency bands in a predetermined order.

4. The radar detector of claim 1, wherein the display screen further comprises a second row having a second plurality of character positions arranged in a linear manner, wherein the storing means includes means for storing a plurality of predefined characters, and wherein the driving means includes means for driving the display screen to display at least one predefined character in the second row in response to the detected microwave signal.

5. The radar detector of claim 1, wherein the identifying means includes means for identifying a first magnitude of at least one additional characteristic of the detected microwave signal, and wherein the scaling means includes means for scaling each character position in a vertical manner to correspond with a range of the at least one additional characteristic, and wherein the driving means includes means for driving the display screen to display the first predefined character in the character position in the first row which corresponds to the identified segment and with a vertical scaling corresponding to the first magnitude.

6. The radar detector of claim 5, wherein the at least one additional characteristic is an amplitude of the detected microwave signal.

7. The radar detector of claim 5, wherein the at least one additional characteristic is a signal strength of the detected microwave signal.

8. A radar detector, comprising:

a display screen including means for defining a plurality of character positions geometrically across the display screen,

a microwave detection circuit having means for means for detecting a microwave signal within at least one predefined microwave frequency band and for generating at least a first output signal indicative of the detected microwave signal,

a laser detection circuit having means for detecting an infrared signal and for generating at least a second output signal indicative of the detected infrared signal,

means for storing a plurality of predefined characters including a plurality of predefined text messages,

control means for selecting a predefined text message in response to the first output signal or the second output signal, and

means for driving the display screen to display the selected predefined text message.

9. The radar detector of claim 8, further comprising:

the display screen including at least a first row having a first plurality of character positions arranged in a linear manner,

means for scaling the first row to correspond to the at least one predefined microwave frequency band, wherein each of the first plurality of character positions is scaled to correspond to a contiguous segment of the predefined microwave frequency band,

means for identifying the contiguous segment of the predefined microwave frequency band in which the microwave signal is detected,

means for driving the display screen to display a predefined character in the character position in the first row which corresponds to the identified segment.
