Abstract
A system for testing a radar under test is provided. The system comprises an antenna array with a plurality of antenna elements, a plurality of transceivers downstream to the plurality of antenna elements and a processing unit. In this context, the processing unit is configured to communicate the radar under test by transmitting and/or receiving a two dimensional test pattern and to compare the two dimensional test pattern with a reference pattern.
Claims11
A system for testing a radar under test comprising:
- an antenna array with a plurality of antenna elements;
- a plurality of transceivers correspondingly connected to the plurality of antenna elements;
- and
- a processor;
- and
- wherein the processor is configured to control the system to perform reception testing of the radar under test by (i) controlling the gain and phase of the plurality of transceivers to generate a first radiation pattern to simulate a radar reflection on the radar under test, (ii) controlling transmission, via the antenna array, of the first radiation pattern to the radar under test, wherein the first radiation pattern corresponds to a digital image and is in the form of a first complex radio frequency image, (iii) receiving, via the antenna array, a second radiation pattern from the radar under test, and (iv) analyzing the second radiation pattern with respect to a known test pattern of the digital image.
3 more elements
A method for testing a radar under test comprising the steps of:
- performing reception testing of the radar under test using a test system, by (i) controlling the gain and phase of a plurality of transceivers of the test system to generate a first radiation pattern to simulate a radar reflection on the radar under test, (ii) transmitting, via an antenna array of the test system, the first radiation pattern to the radar under test, wherein the first radiation pattern corresponds to a digital image and is in the form of a first complex radio frequency image, (iii) receiving, via the antenna array, a second radiation pattern from the radar under test, and (iv) analyzing the second radiation pattern with respect to a known test pattern of the digital image.
