Abstract

A radar parking detection system with a Ultra Wide Band (UWB) detection and transmission system including a hardened radar device placed in the vicinity of a parking space to be monitored by using measurements of time delays observed in the reflection of radio waves reflected from objects in the proximity of the transmitted waves and further including a hardened electronic sensor using (UWB) frequencies to determine the presence or absence of a vehicle in the parking space at close range; and a radio transmitter using multiple data transmission to limit the amount of lost data and to communicate changes in status of the parking space.

Claims

1. A Radar Parking Detection System, comprising:

an Ultra Wide Band detection and transmission system including a hardened radar device placed in the vicinity of a parking space to be monitored by using measurements of time delays observed in radio waves reflected from objects in the proximity of the transmitted waves;

said radar detection system including a hardened electronic sensor using Ultra Wide Band frequencies to determine the presence or absence of a vehicle in the parking space at close range;

a radio transmitter using multiple data transmission to limit the amount of lost data and to communicate changes in status of the parking space and the Ultra Wide Band detection and transmission system in which the multiple transmissions use random pause lengths between each transmission attempt; and

said radio transmitter also transmits the operability of said detection and transmission system.

2. A Radar Parking Detection System as in claim 1, wherein the [UWB] Ultra Wide Band detection and transmission system is packaged in a low-profile shell made of glass-filled nylon or some other similar substance and mounted to the surface of the parking space using a high-tensile strength adhesive and mounting screws to ensure the integrity of the low-profile shell.

3. A Radar Parking Detection System as in claim 2, further comprising an antenna, mechanical subsystem and power subsystem and wherein the sensing subsystem, transmitting system, power subsystem, the antenna and mechanical subsystem are enclosed in said low-profile shell.

4. A Radar Parking Detection System as in claim 1, wherein said detection and transmission system is placed in at least one of the roadbed of the parking space, the bordering curb or parking bumper in the front and to the side of the parking space.
