A monostatic radar device includes a first channel with a first bandwidth, configured to receive a first radar signal, and a second channel with a second bandwidth, configured to receive a second radar signal. The first frequency band and the second frequency band are different from each other. The device includes control circuitry configured to obtain a first channel response associated with the received first signal at the first channel and obtain a second channel response associated with the received signal at the second channel, and combine the first channel response with the second channel response by channel stitching to obtain a combined channel response.
A radar device (100) being a monostatic radar device, comprising:
The radar device (100) according to one of the preceding claims,
The radar device (100) according to one of the preceding claims, wherein the control device (110) is further configured to:
The radar device (100) according to one of the preceding claims, comprising three or more channels (121-124), and
The radar device (100) according to one of the preceding claims, further comprising:
The radar device (100) according to one of the preceding claims, comprising at least one of the following features:
The radar device (100) according to one of the preceding claims, wherein the combined channel response (115) has a peak-to-sidelobe-ratio, PSLR, of 20 dB or higher.
A method of operating a radar device (100) being a monostatic radar device, the method comprising:
Using channel stitching to improve the channel impulse response, CIR, resolution of an ultra-wideband, UWB, radar device.
