Embodiment Construction

[0030] figure 1 A block diagram of a radar system 100 including a radar unit 110 and a base station 111 according to an embodiment of the disclosure is shown. In various embodiments, radar system 100 may be configured for use on a ship, aircraft, vehicle, or in a fixed location or other environment, and may be used in a variety of applications, such as, for example, recreational navigation, commercial navigation, Military navigation or other types of navigation. In one embodiment, radar unit 110 may be implemented as a relatively compact portable unit that is conveniently installed by a user.

[0031] As further described herein, radar unit 110 may be implemented to broadcast radar signal 105 and receive return signal 108 in response thereto. Radar unit 110 may communicate wirelessly with base station 111 via wireless signal 109 to provide, eg, radar data corresponding to return signal 108 to base station 111 . This wireless communication can be accomplished according to va...

Abstract

Various techniques are disclosed for providing a radar system. In one example, such a radar system includes a radar unit adapted to broadcast radar signals and receive return signals in response thereto. The radar unit includes a waveform generator adapted to provide pulse waveforms of different pulse widths and Frequency Modulated Continuous Wave (FMCW) waveforms, wherein the waveforms are interleaved with each other to provide a transmission sequence for the radar signals for detection of long range and short range targets, a power amplifier adapted to amplify the radar signals for broadcast, and an antenna adapted to broadcast the radar signals and receive the return signals. Other examples of radar systems and related methods are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 581,989, entitled "RADAR SYSTEM PROVIDING MULTIPLE WAVEFORMS FOR LONG RANGE AND SHORT RANGE TARGET DETECTION," filed December 30, 2011, which is incorporated by reference in its entirety merged here. technical field [0003] One or more embodiments of the invention relate generally to radar systems, and more particularly to, for example, solid-state radar technology. Background technique [0004] Radar systems are commonly used to detect objects (eg, objects, geographic features, or other types of objects) in close proximity to ships, aircraft, vehicles, or fixed locations. Conventional radar systems typically employ magnetrons to generate radar signals. Unfortunately, magnetrons and their associated microwave hardware structures are often expensive, bulky, and require large power supplies to operate. Therefore, magnetron-based radar s...
