Electronic manufacturers are doing all they can to invent more effective and efficient systems for your on board electronics and radar manufacturers are no different. From Digital radar giving a more digitizes picture to the advances in Broadband radar using solid state technology with zero rad-haz and instant on . See below for a round up of the different system.
Digital radar works by transmitting long radiated signals using solid state equipment. This requires less power and can be processed digitally. With returning echoes varying in strength dependent on what they are bouncing off, being able to process the echoes helps improve the quality of the signal and its usability.
The digitized echoes can be represented on colour high definition screens. In these cases the reliability of the echo signal can be colour coded to help guide the user. Given the lack of moving parts, digital radar should become cheaper to buy, run and maintain over time.

Raymarine Quantum Radar, by FLIR, is the next generation of marine radar featuring CHIRP pulse compression technology. Setting a new standard for compact solid state radar, Quantum delivers superior radar imaging on both long and extremely short ranges
The manufacturers of the new Broadband Radar claim it has many benefits over conventional radar including; low power, low radiation emission, no radar warm up time, clearer picture and little tuning required. Bold words indeed, but how do they do it?

Using advanced Doppler processing, the system instantly highlights moving radar contacts and color codes them to indicate whether they are inbound or outbound. Quantum with Doppler makes it easy to discern potentially dangerous targets when navigating in high-traffic areas.
