Problems solved by technology

Typically, above a limit (such as 85 degrees Celsius), circuit operation must be stopped because either it will not function properly, or it may even be damaged, rendering it inoperable when the temperature returns to its normal operating range
In addition, continued operation itself can exacerbate temperature problems, as such radar units generate heat during operation which, if operated at temperatures above the normal operating range, may further increase the temperature, exacerbating the deleterious effects of high temperatures

Embodiment Construction

[0031] The radar device according to the first embodiment of the present invention is shown in the drawings figure 1 shown in . The radar device comprises a signal generating unit 1 in the form of an oscillator, which generates a radar signal. The signal generating unit 1 has an output coupled to a transmitter circuit 2 which itself is coupled to a transmitting antenna 3 .

[0032] The transmitting antenna 3 is arranged to transmit radar signals into an area where a target 4 may be present. The radar signal reflected from the target 4 is received by the receiving antenna 5 and processed by the receiving circuit 6 and transmitted to the mixer 7, which downmixes the received radar signal and a part of the generated radar signal for the Processor 8 processes.

[0033] A control unit 9 such as a microprocessor controls the operation of the radar device. A radar device is housed within a housing 11 .

[0034] The radar device is also provided with a temperature sensor 10, such...

Abstract

A radar apparatus includes a signal generation unit and a temperature sensing means. The signal generation unit is arranged to generate radar signals at an output power and has an output for the radar signals. The temperature sensing means has an output and is arranged to produce an output signal indicative of a temperature of at least part of the radar apparatus. The output of the temperature sensor is coupled to the signal generation unit. The signal generation unit is configured so the output power is a first power when the output signal is indicative of a temperature within a first temperature range and is a second power lower than the first power when the output signal is indicative of a temperature within a second temperature range higher than the first temperature range.

Description

technical field [0001] The invention relates to a radar device and to a method of operating such a device. Background technique [0002] Radar devices, especially for automotive applications such as automatic cruise control or automatic emergency braking, are well known. Typically, they include a radar signal source, a transmitter for the radar signal, and receiving and processing equipment. Such a system is known, for example, from PCT patent application published as WO2004 / 053521. [0003] However, especially where such radar devices are deployed in harsh environments like the engine compartment of a car, they must only have a limited temperature range in which they will operate. Typically, above a limit (such as 85 degrees Celsius), circuit operation must be stopped because either it will not function properly, or it may even be damaged, rendering it inoperable when the temperature returns to its normal operating range. in addition, continued operation itself can exace...
