A housing for a radar sensor module has a back surface and a plurality of side surfaces connected to the back surface. A vent structure is connected to the back surface and at least one of the side surfaces. The vent structure includes an enclosure enclosing a chamber. A first opening in the vent structure penetrates the at least one of the side surfaces of the housing, such that the chamber is exposed to an exterior of the housing. A second opening in the vent structure penetrates the enclosure such that the chamber is exposed to an interior of the housing.

Methods and systems for correcting leakage and/or distortion in radar systems include defining an integration time period, dividing the integration time period into a first sub-period and a second sub-period, at least partially transmitting a transmission radar signal during the first sub-period of the integration time period, not transmitting at all during the second sub-period of the integration time period, integrating the detected signal during both the first sub-period and the second sub-period, and subtracting a last sampled integrated value of the second sub-period from a last sampled integrated value of the first sub-period to generate a corrected integrated value for the integration time period.

Systems and methods for correcting for leakage and distortion in radar systems

An apparatus for determining the position of a target object using a two-channel monopulse radar. The radar may include two transmitting antennas and one common receiving antenna disposed in a coplanar arrangement. The transmitting antennas may be positioned on the focal plane of the radar along a focal plane axis that extends through, and that is perpendicular with, a boresight axis of the radar. The transmitting antennas may be spaced apart from one another in a first dimension a distance equal to about one half of one wavelength of the radar's center operating frequency. One of the transmitting antennas may be squinted at an angle of &#x3b8;relative to the boresight axis and the other transmitting antenna may be squinted at an angle of &#x3b8;relative to the boresight axis in a second dimension. The transmitting antennas are not squinted relative to one another in the first dimension.
